I'm trying to make sense of my DNA results. I sent two YDNA samples to FTDNA for 67 markers to see if a family I've researched through traditional genealogy methods is related to mine.
One sample is my brother's, the other is a man whose line I have researched and connected to mine through census and other records. I think his gggrandfather, Alexander, whose brother was John, was uncle to my great grandfather, James Alexander, and raised him from a small child. What I can't prove through traditional sources is that James Alexander was the son of John.
My brother matched 65 of 67 markers of the second sample and is considered a genetic distance 2. Both samples have the surname Williams. The relationship on paper connects at the fifth generation.
Even though I can't connect the two families on paper, can I still be assured that we are related at the fifth generation?
