Fishing for DNA

Have you thoroughly fished your family DNA pool? The experts of DNA repeatedly remind us to test the oldest generation and to test everyone we can. My latest fishing trip proved that theory in a very dramatic way. Rather than bore you with numbers, let me introduce the fish in this little DNA pool.

My cousin Connie, the woman who had the miracle Civil War era letter, had done an autosomal DNA test at MyHeritage, as had I. A comparison of Connie's match to my Dad (salmon), my uncle (purple) and me (blue) turned up small, but respectable matches.

Connie had not tested her older generation. She and I discussed testing options for her elderly family members and she decided to test them at MyHeritage, also.

Connie's Dad showed a stronger match to all of my tests, as we would expect. My Dad's fish is yellow, while my uncle's is gray and mine is blue.

Taking the extra step and paying the extra cost to test more relatives paid off dramatically. Her uncle had the strongest match to every member of my family. My uncle had the strongest match (turquoise), while my Dad and I had a smaller, but identical, match. The uncle to uncle match actually provided the most information.

Connie's uncle is missing one segment on chromosome 11 that all the rest of us inherited. He provides several other matching segments, on five different chromosomes, to help us with identifying more cousin matches in our Taylor line.

Of course, for those of you who want to see the centimorgan (cM) numbers, here they are.

If you haven't fished your DNA pool yet, the holiday specials should be starting in a few weeks. It's time to go fishing!
