My Jones surname DNA had 26 exact 12 marker matches. Where in the world are they? An exact 12 marker test showed that our most recent common ancestor (MRCA) was some 29 generations ago! [95% chance] Who in this world has their genealogy traced back 29 generations?
Being an exception to the rule, my years of genealogy research [now 51 years], has traced my family's line back 53 generations. Given in a series of previous posts, starting with "The Beginnings (generations 1-5)" [March 23, 2011] and ending with "Finally There (generation 45 - "Pap paw" [April 29, 2011], the generations are presented. My 29th generation grandfather is Ynyr ap Gadforch (JB-1). This would take our common ancestor back to around 900 A.D.! He was the father of Tudor Trevor (JC- 1) who is given credit for "founding" our tribe.
Of the 26 exact 12 marker test the following was found:
Scotland = 5 matches
England = 4 matches
Germany = 3 matches
France, Ireland, Netherlands, Turkey, United Kingdom = 2 match each
Wales, Ukraine, Slovakia, and Albania = 1 match each.
Wow, what a number of countries that share my 12 marker test. Ynyr ap Gadforch descendants sure got around!
Now there were many, many more who matched 11/12 markers. This would go back to generation 47. In my family tree this would be Enid (Jq-1) going back to the early days of Roman occupation! [ca. 150 - 200 A.D.] From this ancestor, there were 168 "1-step" in Ireland, 156 in England, 122 in Scotland, 88 United Kingdom, 66 Germany, 36 Netherlands, 36 France, 22 Wales, 19 Spain, 13 Italy, and 11 Switzerland.
My R1b1b2 [now classified R1b1a2]...it is definitely in the world.

Well, It's About Time
As a genealogist, having my own DNA analyzed was at first a hard decision to make. I had spent 50 years reseaching my family tree using the old library method, and blood hound techniques. This produced results that I felt were pretty accurate. Or were they? DNA was to prove me right or wrong? What if all my research proved to be wrong? I had traced my JONES surname back to Wales. What if DNA showed I was from China? Oh man, maybe I sould leave this DNA stuff alone?
It took several years to decide to go ahead and have my DNA tested. It only took a couple of months to get the results. Twenty five exact matches for my 12-marker test! I've hit the jackpot! Well let's see who are these folks? There is a Claxton, Amshoff, Boyle, Tilton, Mauradoglu(x2), Dohanrich, Sharp(x2), Gilmore, Welrich, Johnson(x2), Prichard, Gill(x2), Leonard, Pearson, Maudire-Janton, Fournier, and only one other JONES! What in the world? I had never heard of most of these surnames! How could I have exact 12-marker DNA.
An explaination which came with the results stated: "...if you match another person exactley with the same surname or a variant, you have a 99.9% likelihood of sharing a common ancestor with that person." This information went on to say, "This individual is described scientifically as the Most Recent Common Ancestor (MRCA)." A graph was included that gave an estimate of how long ago this common ancestor lived. The graph showed that on a 12/12 match, "...a 90% probablity that the MRCA lived no longer than 23 generations"! There was a 95% probabitity that the MRCA lived no longer 29 generations.
No longer than 23 generations! Not many folks would have their genealogy past 6-8 generations. Maybe the next series of DNA markers will help? Well maybe, it's not about time yet?
My 12-marker test as reported:
