DNA and Genealogy
The first news is so far I have found NO NPE in either line. What is an NPE? Non Parental Event.1 In other words, my paper records do agree with DNA. All lines have been confirmed to around the mid 1700s or as far as I have been able to go. I need to learn more about using DNA results to try to find our last few missing “recent” ancestors. One is the wife of John Ratliff (ca 1805-1847), my third great grandfather. I’m also not sure of his parents, but from DNA I know who his grandparents are. Also, I do not know for sure who the parents of our second great grandfather Alexander Anderson (1805-1884) is. We think the name is Archibald, but I cannot be sure of a suitable person in the records. The good news is I have a clue that might work out. We do know the ancestry of his wife.
The chart below is how ancestry.com displays something they call Thrulines, and is so far the most important way that I am using the DNA information. What they do is compare DNA matches with me to other people’s ancestry trees comparing them to my tree. In this case it works pretty well because Robert Davis’ ancestry is well known and that means most people’s trees are reasonably correct. I conclude from this that I am related to 5 children of Robert Davis. That does not prove the name of Robert Davis, but does provide confirmation that I am related to 4 other children who we believe are children of Robert Davis. I say this because sometimes we do know the names of the children, but not the parent’s name, usually in the case of missing or incorrect wife’s name. All I know is I am related to 78 other people who claim to descend from Robert Davis. But in this easy case, this is sufficient for my purposes, which is to confirm that Robert Davis is my ancestor.
