For the past several weeks, I’ve been describing a project for which I used various types of analysis to attempt to clarify the uncertain paternal ancestry of someone I’m calling “Bob” (all names in these posts have been changed for privacy). In this post, I’ll summarize the results of the analyses in the previous posts... Continue Reading →
To predict the most likely locations for someone in a family tree (relative to DNA matches with a common ancestor), I've used the What Are The Odds? Tool to thoroughly test hypothetical trees and determine more or less likely relationships. As a complement to documentary research of a family, this has helped me narrow down paternal candidates for someone with uncertain genetic ancestry.
Last week, I described using autosomal DNA matches, their relationships to each other, and their trees to start to construct a new family tree for someone (“Bob”) with uncertain paternity. The most recent common ancestor (MRCA) for Bob and some of these matches appears to be a woman born about 115 years before Bob, who... Continue Reading →
