4458 and 4570 don't match on all twelve markers, so, genealogically speaking, we're probably not related. However, as we do match on eight out of twelve markers, there is a possibility that we do still share a common ancestor who may have lived about 3,500 years or so ago. This is the opinion of an "expert" I consulted. So, for our purposes, nothing useful, so far. In comparing 12 markers, the probability that 4458 and 4570 shared a common ancestor within the last 100 years is 0.00%. Within the last 200 years = 0.08%, 300 years = 0.43%, 400 years = 1.30%, 500 years = 2.95% and within 600 years = 5.53%.

The results for 4571 are only one mutation step away from a match with 4458. This mutation could have occurred at any time during the last 1,000 years, but it could have occurred much more recently, say, a few centuries ago. There is no way of knowing exactly when. There is probably a common ancestor at some point in the past, but it is probably too long ago to be genealogically useful. In comparing 12 markers, the probability that 4571 and 4458 shared a common ancestor within the last 100 years is 7.14%; within the last 200 years = 20.09%; within 300 years = 34.36%; within 400 years = 47.74%; within 500 years = 59.32% and within 600 years = 68.87%.

Results for 5419 and 5482 don't appear to match anyone. The nearest to 5419 is 4570, which is 3 mutation steps distant. The nearest to 5482 is also 4570, which is also 3 steps away. So, 5419 and 5482 appear to have more in common with 4570 than they do with each other or with anyone else in the study, though there is still virtually no relationship. In comparing 12 markers, the probability that 5419 and 4570 shared a common ancestor within the last 100 years is 0.05%; within 200 years = 0.55%; within 300 years = 1.98%; within 400 years = 4.68%; within 500 years = 8.71% and within 600 years = 13.93%.

The probability that 5482 and 4570 shared a common ancestor within 100 years is 0.05%; within 200 years = 0.51%; within 300 years = 1.85%; within 400 years = 4.40%; within 500 years = 8.22% and within 600 years = 13.20%.

7180 is not related to anyone in the study. He comes nearest to 5677, by 8 mutation steps. In comparing 12 markers, the probability that 7180 and 5677 shared a common ancestor within the last 100 years is 0.00%; within 200 years = 0.00%; within 300 years = 0.00%; within 400 years = 0.00%; within 500 years = 0.00% and within 600 years = 0.01%.

5265 ordered the 25-marker test. The remaining 12 alleles for this member are: 17, 8, 9, 11, 11, 29, 16, 19, 29, 14, 16, 16, 19. Note that the first 12 markers are not a match to anyone currently in the study. The nearest to 5265 are 4570 and 4571, though each is 14 mutation steps away from 5265. In comparing 12 markers, the probability that 5265 and 4570 shared a common ancestor within the last 100 years is 0.00%; within 200 years = 0.00%; within 300 years = 0.00%; within 400 years = 0.00%; within 500 years = 0.00% and within 600 years = 0.00%.

The probability that 5265 and 4571 shared a common ancestor with the last 100 years is 0.00%; within 200 years = 0.00%; within 300 years = 0.00%; within 400 years = 0.00%; within 500 years = 0.00% and within 600 years = 0.00%.

5604 is a 12/12 match with 5419, and note that they share the same surname spelling (Rhea), as well. These two are related. In comparing 12 markers, the probability that 5604 and 5419 shared a common ancestor within the last 100 years is 33.57%; within the last 200 years = 55.88%; within 300 years = 70.69%; within 400 years = 80.53%; within 500 years = 87.07% and within 600 years = 91.41%. This would indicate the MRCA most likely lived sometime during the 1400s (15th century).

5234 doesn't match anyone currently in the project. The closest he comes is to 5482, who is 11 steps distant. In comparing 12 markers, the probability that 5234 and 5482 shared a common ancestor within the last 100 years is 0,00%; within 200 years = 0.00%; within 300 years = 0.00%; within 400 years = 0.00%; within 500 years = 0.01% and within 600 years = 0.02%.

5677 doesn't match anyone, the nearest to him being 5482, who is 11 steps distant. So, no relationship here, either. In comparing 12 markers, the probability that 5677 and 5482 shared a common ancestor within the last 100 years is 0.00%; within 200 years = 0.00%; within 300 years = 0.00%; within 400 years = 0.00%; within 500 years = 0.00% and within 600 years = 0.01%.

7348 doesn't match anyone. He comes closest to 4570 (2 steps away), and is 3 steps distant from 5419, 5482 and 5604. In comparing 12 markers, the probability that 7348 and 4570 shared a common ancestor within the last 100 years is 0.83%; within 200 years = 4.31%; within 300 years = 10.59%; within 400 years = 18.93%; within 500 years = 28.38% and within 600 years = 38.12%.

7180 is closest to 5677, by 8 steps. Not close enough to really call it a relationship. If they are related, the common ancestor would have been very long ago, probably in prehistoric times. In comparing 12 markers, the probability that 7180 and 5677 shared a common ancestor within the last 100 years is 0.00%; within 200 years = 0.00%; within 300 years = 0.01%; within 400 years = 0.05%; within 500 years = 0.17% and within 600 years = 0.44%.

12766 comes closest to 7348 (3 steps away), which would indicate that, if there is a common ancestor between these two, it was most likely prior to the advent of hereditary surnames, and thus, not genealogically useful. The same goes for 10546 and 5482, who are also three steps apart. In comparing 12 markers, the probability that 12766 and 7348 shared a common ancestor within the last 100 years is 0.08%; within 200 years = 0.77%; within 300 years = 2.74%; within 400 years = 6.33%; within 500 years = 11.51% and within 600 years = 18.01%.

13689 does not match with anyone. The closest he comes is within 2 steps of 5482. 13689 used the 25-marker test. The remaining 12 alleles for this member are: 17, 9, 10, 11, 11, 25, 15, 18, 30, 15, 15, 16, 17. The first 12 markers are found in the chart above. In comparing 12 markers, the probability that 13689 and 5482 shared a common ancestor within the last 100 years is 0.78%; within 200 years = 4.09%; within 300 years = 10.11%; within 400 years = 18.14%; within 500 years = 27.32% and within 600 years = 36.84%.

12499 does not match anyone. The closest he comes to a match is with 5677, which is within 6 steps. In comparing 12 markers, the probability that 12499 and 5677 shared a common ancestor within the last 100 years is 0.00%; within 200 years = 0.00%; within 300 years = 0.04%; within 400 years = 0.16%; within 500 years = 0.46% and within 600 years = 1.05%.

23063 does not match anyone. The closest he comes is 8 steps from 5265. In comparing 12 markers, the probability that 23063 and 5265 shared a common ancestor within the last 100 years is 0.00%; within 200 years = 0.00%; within 300 years = 0.00%; within 400 years = 0.01%; within 500 years = 0.04% and within 600 years = 0.11%.

26343 doesn't match anyone, that I can see. I say, "that I can see," because I had to check his alleles against everyone else's the "hard way." He has come to our project through the back door, so to speak, by having his DNA tested individually, outside any surname project. The only way I knew he existed at all was because he emailed me, requesting to have his alleles added to our study. This is not a good thing, as it makes it impossible for FTDNA to track his results in comparison to the rest of us, since he is not listed as a participant in the Rea Surname DNA Project. In other words, from now on, I will have to visually compare his alleles with everyone else's to see if he has matched anyone - or he will have to do so himself (which I recommend, as I don't have the time and patience to mess with it!). Let this be a lesson to anyone contemplating having himself tested! Just join the project, please; it will make life easier for all of us.

473 and 5265 are a 12/12 match. 473 was tested prior to the founding of the project and was recently added. In comparing 12 markers, the probability that 473 and 5265 shared a common ancestor within the last 100 years is 33.57%; within 200 years = 55.88%; within 300 years = 70.69%; within 400 years = 80.53%; within 500 years = 87.07% and within 600 years = 91.41%.

30053 comes closest to 7348, who is 2 steps away. In comparing 12 markers, the probability that 18603 and 13689 shared a common ancestor within the last 100 years is 0.82%; within 200 years = 4.27%; within 300 years = 10.51%; within 400 years = 18.80%; within 500 years = 28.21% and within 600 years = 37.91%.

22416 doesn't match anyone, so far. The closest he comes is 8 steps from 18254. In comparing 12 markers, the probability that 22416 and 18254 shared a common ancestor within the last 100 years is 0.00%; within 200 years = 0.00%; within 300 years = 0.01%; within 400 years = 0.03%; within 500 years = 0.11% and within 600 years = 0.30%.

35499, 10546 and 24007 are the first three-way 12/12 match in the history of the project. In comparing 12 markers, the probability that 35499, 10546 and 24007 shared a common ancestor within the last 100 years is 33.57%; within 200 years = 55.88%; within 300 years = 70.69%; within 400 years = 80.53%; within 500 years = 87.07% and within the last 600 years = 91.41%. It is recommended all three use the 25 or 37-marker test to narrow down the timeline further.

33425 comes closest to 18254, who is 2 steps away. In comparing 12 markers, the probability that 33425 and 18254 shared a common ancestor within the last 100 years is 0.90%; within 200 years = 4.67%; within 300 years = 11.39%; within 400 years = 20.21%; within 500 years = 30.09% and within the last 600 years = 40.15%

N1959 has a 12-marker match with 23031 and 4570. This is significant, in that, one of the two members he matches is a McCrea, proving yet another link between Reas/Rays and the Clan MacRae. In comparing 12 markers, the probability that N1959, 23031 and 4570 shared a common ancestor within the last 100 years is 33.57%; within 200 years = 55.88%; within 300 years = 70.69%; within 400 years = 80.53%; within 500 years = 87.07% and within the last 600 years = 91.41%

N11085 is a 12-marker match with 29725 and 30053. In comparing 12 markers, the probability that N1959, 23031 and 4570 shared a common ancestor within the last 100 years is 33.57%; within 200 years = 55.88%; within 300 years = 70.69%; within 400 years = 80.53%; within 500 years = 87.07% and within the last 600 years = 91.41%

N13937 is one mutation step away from 10546, 24007, 35499 and 36379. In comparing 12 markers, the probability that N13937, 10546, 24007, 35499 and 36379 shared a common ancestor within the last 100 years is 6.67%; within 200 years = 18.94%; within 300 years = 32.64%; within 400 years = 45.68%; within 500 years = 57.13% and within the last 600 years = 66.71%.

In comparing 25 markers, the probability that 55885, 473, 47822 and 5265 shared a common ancestor within the last 4 generations is 33.57%; within 8 generations = 55.88%; within 12 generations = 70.69%; within 16 generations = 80.53%; within 20 generations = 87.07% and within the last 24 generations = 91.41%.

53670 is 3 mutation steps away from 56879. In comparing 25 markers, the probability that 53670 and 56879 shared a common ancestor within the last 4 generations is 0.07%; within 8 generations = 0.72%; within 12 generations = 2.57%; within 16 generations = 5.96%; within 20 generations = 10.89% and within the last 24 generations = 17.12%.

60464 is a 12-marker match with both 7348 and 53848. In comparing 25 markers, the probability that 60464, 7348 and 53848 shared a common ancestor within the last 4 generations is 33.57%; within 8 generations = 55.88%; within 12 generations = 70.69%; within 16 generations = 80.53%; within 20 generations = 87.07% and within the last 24 generations = 91.41%.

64249 is a 12/12 match with 473, 47822, 5265 and 55885. In comparing 12 markers, the probability that 64249, 473, 47822, 5265 and 55885 shared a common ancestor within the last 4 generations is 33.57%; within 8 generations = 55.88%; within 12 generations = 70.69%; within 16 generations = 80.53%; within 20 generations = 87.07% and within the last 24 generations = 91.41%.

63926 does not match anyone. The closest he comes to it is two steps away from 59304. In comparing 12 markers, the probability that 64249, 473, 47822, 5265 and 55885 shared a common ancestor within the last 4 generations is 0.81%; within 8 generations = 4.24%; within 12 generations = 10.43%; within 16 generations = 18.67%; within 20 generations = 28.03% and within the last 24 generations = 37.7%.

12766 has a 25-marker match with 39901. In comparing 25 markers, the probability that 12766 and 39901 shared a common ancestor within the last 4 generations is 33.57%; within 8 generations = 55.88%; within 12 generations = 70.69%; within 16 generations = 80.53%; within 20 generations = 87.07% and within the last 24 generations = 91.41%.

In comparing 25 markers, the probability that 56879 and N32416 shared a common ancestor within the last 4 generations is 6.81%; within 8 generations = 19.28%; within 12 generations = 33.15%; within 16 generations = 46.3%; within 20 generations = 57.79% and within the last 24 generations = 67.37%.

12499 does not match anyone, yet. He comes closest to 5677, who is 6 mutation steps away. In comparing 12 markers, the probability that 12499 and 5677 shared a common ancestor within the last 4 generations is 0.00%; within 8 generations = 0.00%; within 12 generations = 0.04%; within 16 generations = 0.16%; within 20 generations = 0.46% and within the last 24 generations = 1.05%.

55885 is a 25-marker and 37-marker match with 473, 47822, 5265 and 64249. See above for FTDNATiP report on their 12-marker match, which occurred earlier.

80052 is one mutation step away from 10546, 24007, 35499, 48387 and 63329. In comparing 12 markers, the probability that 80052, 10546, 24007, 35499, 48387 and 63329 shared a common ancestor within the last 4 generations is 6.81%; within 8 generations = 19.28%; within 12 generations = 33.13%; within 16 generations = 46.3%; within 20 generations = 57.79% and within the last 24 generations = 67.37%.

83649 is a 25-marker match with 12766. In comparing 12 markers, the probability that 83649 and 12766 shared a common ancestor within the last 4 generations is 33.57%; within 8 generations = 55.88%; within 12 generations = 70.69%; within 16 generations = 80.53%; within 20 generations = 87.07% and within the last 24 generations = 91.41%.

90210 is one mutation step away from both 5419 and 5604. This near-match is yet another confirmation of the connection between Reas/Rheas, etc. and their possible descent from the Clan MacRae. In comparing 12 markers, the probability that 90210, 5419 and 5604 shared a common ancestor within the last 4 generations is 6.81%; within 8 generations = 19.28%; within 12 generations = 33.15%; within 16 generations = 46.3%; within 20 generations = 57.79% and within the last 24 generations = 67.37%.

100274 is a 12-marker match with 5234 and 72844. In comparing 12 markers, the probability that 100274, 5234 and 72844 shared a common ancestor within the last 4 generations is 33.57%; within 8 generations = 55.88%; within 12 generations = 70.69%; within 16 generations = 80.53%; within 20 generations = 87.07% and within the last 24 generations = 91.41%.

N54232's 25-marker results do not show a match with anyone, yet. Previously, he has a 12-marker match with 23031, 4570 and N1959. Of these three, only 23031 has used the 25-marker test, so far, and there is no match between the two on markers 13 through 25. So, in the case of N54232 and 23031, the 25-marker test yields no improvement in narrowing down the time of their most recent common ancestor (MRCA).

100274 is a 67-marker match with 72844. They match on the in 60, 61, 62, 63, 64, 65, 66 or 67 loci, which means that there is a 99% likelihood of them sharing a common ancestor.

5234 is a 25-marker match with 97251, 100274 and 72844. This group has previously been tested and knew they had a 12-marker match, so, this match at the 25-marker level pretty much confirms they are related. The really interesting thing is that one of them has a surname other than Ray/Rea and, not only that, but all have several matches to men of the surname Boyd. This would tend to indicate that all four men descend from a common Boyd ancestor and that, somehow, possibly via adoption, they all descend from a Boyd who was given the name Ray or took it for himself at some point.

109592 has a 25-marker match with 12766 and 83649. In comparing 12 markers, the probability that 12766, 39901, and 83549 shared a common ancestor within the last 4 generations is 33.57%; within 8 generations = 55.88%; within 12 generations = 70.69%; within 16 generations = 80.53%; within 20 generations = 87.07% and within the last 24 generations = 91.41%.

112343 and 5482 are a 12-marker match. In comparing 12 markers, the probability that 12766, 39901, and 83549 shared a common ancestor within the last 4 generations is 33.57%; within 8 generations = 55.88%; within 12 generations = 70.69%; within 16 generations = 80.53%; within 20 generations = 87.07% and within the last 24 generations = 91.41%.

112900 has no matches but is one mutation step removed from 111873, 11850 and 13689.

15714 comes closest to a match with 13689, missing it by only 2 steps. 15714 is a McCrea, while 13689 is a Rea. This would seem to indicate that 13689 is probably related, at some point, to a member of the Clan MacRae, and thus, his original surname may have been MacCrea or McCrea at one time. Further research is necessary before any conclusions can really be drawn from this. I would recommend both 15714 and 13689 use the 25-marker test to further narrow down the time at which their MRCA (Most Recent Common Ancestor) may have lived. This is an interesting result, as it gives us our first glimpse of a possible Rea - MacRae connection. I'm a little disappointed that the rest of us were so much farther removed from 15714, but perhaps a few of us will match to the lines of other MacRaes. In comparing 12 markers, the probability that 15714 and 13689 shared a common ancestor within the last 100 years is 0.95%; within 200 years = 4.89%; within 300 years = 11.88%; within 400 years = 20.99%; within 500 years = 31.11% and within 600 years = 41.35%.

16464 doesn't match anyone, but comes closest to 4570 and 7348, who are 2 points off. This, like the other MacRae above, neither confirms nor excludes the link between Reas and MacRaes, yet. In comparing 12 markers, the probability that 16464 and 4570 shared a common ancestor within the last 100 years is 0.81%; within 200 years = 4.24%; within 300 years = 10.43%; within 400 years = 18.67%; within 500 years = 28.03% and within 600 years = 37.70%.

The probability that 16464 and 7348 shared a common ancestor within the last 100 years is 0.90%; within 200 years = 4.63%; within 300 years = 11.31%; within 400 years = 20.08%; within 500 years = 29.92% and within 600 years = 39.95%.

11850 is a 12/12 match with 13689. Note that their surname spelling differs (Rhea versus Rea), indicating that, in one line or the other, a spelling change occured at some point and was continued to the present. These two are related. In comparing 12 markers, the probability that 11850 and 13689 shared a common ancestor within the last 100 years is 33.57%; within 200 years = 55.88%; within 300 years = 70.69%; within 400 years = 80.53%; within 500 years = 87.07% and within 600 years = 91.41%. This would indicate the MRCA most likely lived sometime in the 1400s (15th century).

18383 doesn't match anyone, being 5 steps away from 5 of us, at best, and 18 steps from a couple of members. It is interesting, though, that he comes closer to five variously spelled Reas than he does to his fellow MacReas. Hmmm..... In comparing 12 markers, the probability that 18383 and 11850 shared a common ancestor within the last 100 years is 0.05%; within 200 years = 0.51%; within 300 years = 1.85%; within 400 years = 4.40%; within 500 years = 8.22% and within 600 years = 13.20%.

The probability that 18383 and 5482 shared a common ancestor within the last 100 years is 0.72%; within 200 years = 3.80%; within 300 years = 9.44%; within 400 years = 17.06%; within 500 years = 25.84% and within 600 years = 35.04%.

The probability that 18383 and 5604 shared a common ancestor within the last 100 years is 0.06%; within 200 years = 0.61%; within 300 years = 2.20%; within 400 years = 5.17%; within 500 years = 9.56% and within 600 years = 15.18%.

18819 doesn't match anyone, but he comes within a single step of 5419 and 5604. I recommend all three of you should get the 25-marker test done as soon as possible. This will help narrow down any possible relatedness between you. In comparing 12 markers, the probability that 18819 and 5419 shared a common ancestor within the last 100 years is 6.67%; within 200 years = 18.94%; within 300 years = 32.64%; within 400 years = 45.68%; within 500 years = 57.13% and within 600 years = 66.71%.

The probability that 18819 and 5604 shared a common ancestor within the last 100 years is 6.67%; within 200 years = 18.94%; within 300 years = 32.64%; within 400 years = 45.68%; within 500 years = 57.13% and within 600 years = 66.71%.

18254 is the farthest from any of us. The nearest he comes is 10 steps away from 12499. This is a very rare set of allele values. Especially unusual is the "15+16" at DYS19. I'm not even sure how to interpret that. Perhaps Bennett Greenspan can answer this. In comparing 12 markers, the probability that 18254 and 12499 shared a common ancestor within 100 years is 0.00%; within 200 years = 0.00%; within 300 years = 0.00%; within 400 years = 0.00%; within 500 years = 0.00% and within 600 years = 0.02%.

20177 isn't related to any of us, so far. The closest he comes is within six steps of 5265. In comparing 12 markers, the probability that 20177 and 5265 shared a common ancestor within the last 100 years is 0.00%; within 200 years = 0.09%; within 300 years = 0.47%; within 400 years = 1.44%; within 500 years = 3.24% and within 600 years = 6.03%.

20177's 25-marker results are even farther distant, coming closest to 5265, who is 21 steps away.

18819's 25-marker results indicate a possible distant relationship to both 5419 and 5604. 18819 is only a single mutation step away from both. This may suggest a relationship that could possibly be confirmed via the 37-marker test. Even so, the relationship may have existed at a time prior to the use of hereditary surnames, so even if relatedness exists between these three, it would be too long ago to be of any genealogical value, as far as finding the Most Recent Common Ancestor (MRCA) is concerned. In comparing 12 markers, the probability that 18819 and 5419 shared a common ancestor within the last 100 years is 6.67%; within 200 years = 18.94%; within 300 years = 32.64%; within 400 years = 45.68%; within 500 years = 57.13% and within 600 years = 66.71%.

The probability that 18819 and 5604 shared a common ancestor within the last 100 years is 6.67%; within 200 years = 18.94%; within 300 years = 32.64%; within 400 years = 45.68%; within 500 years = 57.13% and within 600 years = 66.71%.

23031 and 4570 are a 12/12 match. This is a significant match, as it confirms the descent of a Rea from a line of McCreas, thus establishing a likely connection to Clan MacRae. In order to pin down the time at which the Most Recent Common Ancestor (MRCA) lived, it would be a good idea for 4570 to use the 25-marker test, at this point. 23031's 25-marker results indicate he is only one step away from 18819 at DYS 449, although the report from FTDNA doesn't mention this fact, strangely enough. So, not only is 23031 a 12/12 match with 4570, he is also very close to a 25/25 match with 18819, as well. In comparing 12 markers, the probability that 23031 and 4570 shared a common ancestor within the last 100 years is 33.57%; within 200 years = 55.88%; within 300 years = 70.69%; within 400 years = 80.53%; within 500 years = 87.07% and within 600 years = 91.41%. This indicates the MRCA most likely lived in the 1400s (15th century).

24007 and 10546 are a 12/12 match. There is a relationship at some point in the past. 10546 might consider also using the 25-marker test at this time, in order to narrow down the timeline for the their Most Recent Common Ancestor (MRCA). 25-marker results for 24007 show no matches and the closest he comes to anyone with 25-marker results, at this time, is 8 steps away from 7348. In comparing 12 markers, the probability that 24007 and 10546 shared a common ancestor within the last 100 years is 33.57%; within 200 years = 55.88%; within 300 years = 70.69%; within 400 years = 80.53%; within 500 years = 87.07% and within the last 600 years = 91.41%. This indicates the MRCA most likely lived in the 1400s (15th century).

33441 is a near-match with 11850, 13689 and 5482. There is a probable relationship between these members, but at some point in the distant past. Further testing with the 25 or 37 marker test is required to pin down this down. In comparing 12 markers, the probability that 33441 and 11850 shared a common ancestor within the last 100 years is 6.81%; within 200 years = 19.28%; within 300 years = 33.15%; within 400 years = 46.30%; within 500 years = 57.79% and within the last 600 years = 67.37%.

In comparing 12 markers, the probability that 33441 and 13689 shared a common ancestor within the last 100 years is 6.81%; within 200 years = 19.28%; within 300 years = 33.15%; within 400 years = 46.30%; within 500 years = 57.79% and within the last 600 years = 67.37%.

In comparing 12 markers, the probability that 33441 and 5482 shared a common ancestor within the last 100 years is 6.98%; within 200 years = 19.71%; within 300 years = 33.80%; within 400 years = 47.07%; within 500 years = 58.61% and within the last 600 years = 68.18%. This would tend to indicate the possibility of a relationship with 5482 is slightly higher than for a relationship with either 11850 or 13689.

36379 is a 12/12 match with 10546, 24007 and 35499. In comparing 12 markers, the probability that 33679 and 10546, 24007 and 35499 shared a common ancestor within the last 100 years is 33.57%; within 200 years = 55.88%; within 300 years = 70.69%; within 400 years = 80.53%; within 500 years = 87.07% and within the last 600 years = 91.41%.

63329 is a 12/12 match with 36379, 24007, 10546, 35499 and 48387. This is the line I thought I was descended from, i.e., that of William Rea of Drumskee. As it turns out, I'm seven steps away from 63329, thus, I'm no relation to William Rea. However, I can help those who have matched 63329, as I have a great deal of data on William Rea of Drumskee and the descendants of his eldest son Samuel. The FTDNATiP Report data which follows is off quite a bit, as 63329's "paper trail" and the data I've accumulated over three years will show. Had I been a descendant, myself, I would have been eight generations removed from William. So, the probability of a match within eight generations is really 100% for these five men, as opposed to the 55.88% shown below. For me, it's both a great disappointment and the beginning of a new avenue in my research as I now have some revisions to make. This is a good thing, though, as I have now disproved a myth that has persisted in my family for generations. Isn't science great? In comparing 25 markers, the probability that 56879, 20177 and 23063 shared a common ancestor within the last 4 generations is 33.57%; within 8 generations = 55.88%; within 12 generations = 70.69%; within 16 generations = 80.53%; within 20 generations = 87.07% and within the last 24 generations = 91.41%.
