I think genealogy perhaps is not for me in many ways if DNA testing is revealing family secrets long thought to have been buried forever, and no doubt if I did DNA, it would reveal some many not be my blood ancestors?
I know people will disagree strongly but I always feel if an ancestor is not a blood ancestor, then they are not a real ancestor, as they are not actually responsible for my existence, or anyone else thought to have descended from them.
Shall I just use tracing my ancestry as simply family history instead of hoping I blood descend from ancestors, some of whom I have become attached to for some odd reason. Uncertainty is something I seem hard to accept, even if it is quite small. Since my father died, it has worsened the possibility of my tree having NPE's.
For instance I have a male ancestor who wed a female ancestor when she was 7 months pregnant, and the baby was born 2 months after the wedding (and was christened in the same parish, as the daughter of the man her mother married and the mother herself), in a part of London that was still half rural at the time, and the man came from an area in the country I grew up in but not where my parents are from, so one of my parents has ancestors from the area she moved to, so finding this link made me feel at home, as my family. Going back to the "shotgun" wedding, the baby born during the parents marriage was my direct ancestor, and while it is highly likely the recorded father was the real father, there is always the 1% chance of doubt as with any paternity in a family tree. That 1% doubt is what can niggle away at times, even if the marriage took place over 200 years ago, so the ancestral link is several generations back, so quite a negligible amount of ancestry from the area I grew up in, as it was a 6xgreat grandfather.
