Thomas Cain, still a mystery…

For Christmas last year I took advantage of a sale going on at FTDNA and upgraded my cousin Robert Cain’s DNA results. I upped his yDNA to 111 markers, added the FamilyFinder test, (which will help find cousins), and had some refining marker tests done to suss out more precise information on his haplogroup.

Because Robert passed away a few years ago, his DNA is all we have left of him. And in honor of his memory. and generosity in helping us to find the origins of the CAIN line through DNA, (along with the possibility of his DNA going bad due to time), I wanted to do these tests.

Robert has many yDNA matches, however none of them are less than 5 markers off and none of them are the same surname. So our common ancestor is way, way, way back in time. His updated refined haplogroup designation is:

R-FGC20561

I added Robert’s yDNA results to the R1b Haplogroup Project a few years ago. Recently one of the group’s administrators provided me with a chart that shows Robert’s new place in this project. All the green cells show how his DNA is being refined until we get to the latest test results. Over time yDNA testing will get even more precise.

What does all this mean? Because the haplogroup R1b is such a huge pool of humans, refining the tests helps group results so that DNA matches are more manageable and more accurate. You can see that none of the group of men with Robert have the same last name. It is assumed that the common ancestor of these men was around about 1100AD, before last names really existed in historical documents. So we know who our CAIN ancestor is, just not his name or where he was from or anything else for that matter, just what his yDNA tells us.

The FamilyFinder test, which finds cousins and other relatives, I had done on Robert’s DNA so that I could see where our DNA was matching. This also helps when comparing it to other relatives and cousins to see where we are matching on our Smith/Cain/Rosa lines. Here is an example:

The solid blue/black is Robert, he is the base DNA being compared to. The orange is myself and the light blue is my dad. So you can see what DNA I inherited from the CAIN line that my Dad didn’t, and vice-versa. Ignore the gray bits.

I am not sure how many more tests I will be able to subject Robert’s DNA to, but for now this is a nice improvement on his results. So in a nutshell, we still don’t know the specific origins of Thomas Cain, but we are getting closer.
