Interesting.
I have a challenge in that I have a name of a great-grandfather, but the only evidence of a man by that name is a 1930s census. There is no other record of that man. He was supposedly born around 1880 in Missouri, but I can find no such record. At one point, I got the bright idea that I could check my grandfather’s birth certificate and maybe find there the name of his father. Nope. My grandfather’s birth certificate was filed by his mother in California when he was in his 20s (and he was born in TX). I suspect that whoever my great-grandfather was, he was using a false name.
I hope that by comparing DNA results and finding relatives who have no common name, I may be able to deduce who my great-grandfather really was.
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.
