Do you have siblings or cousins on that side who have tested and can you tell your maternal and paternal apart? I have several testing on ancestry now ($59 was too good to pass up for a black Friday deal). When their results are in I’ll be putting them on gedmatch, ftdna and myheritage. I have several that I share dna with that were adopted or abandoned and are searching for family. We use the tools on gedmatch for detailed information and to show matched areas that ancestry doesn’t.
It might be helpful to be able to match segments of chromosomes against some of my relatives.
One of my problems is that I have a ton of relatives, and well over half—maybe 80%—are related through my grandmother. She was a Mormon, from a big family, and her grandfather or great-grandfather was a polygamist. He was also bodyguard to Joseph Smith, founder of the Mormon religion.
It is her husband, my grandfather, that is the big roadblock in trying to determine my family tree. The trees of three of my grandparents go back to the Massachusetts Bay Colony, with a few roots in the Connecticut Colony. But that fourth grandparent seems to have sprung from nowhere, at least on his father’s side.
I’ve found relatives who are descendants of my grandfather’s half brother, who had a different father. But so far, no one who seems to be related to my Grandpa’s father.
So, yeah, I see a great benefit to matching chromosome segments. If I could get my uncle’s DNA, the information on the Y chromosome would no doubt be very useful, since it would lead directly to Grandpa’s father.
