It's funny, someone contacted me last week on 23 & Me because we were a hit as genetically related (3rd cousins) and he was doing some research on his family tree and wanted my help on filling in some blanks. This was the part of my mom's family that is from west-central PA between the Susquehanna and Pittsburgh. Through the course of the research, I found out two things. First, I have a Civil War era common ancestor (by marriage, the guy who contacted me was a direct descendant) with Jimmy Stewart, who is a local hero in Indiana. I immediately told my son because he's at IUP now and Jimmy Stewart stuff is everywhere there. Second, part of this part of the family tree is from Franklin County near the MD border, which is basically Deliverance country, and there are a couple places where, umm (how to say this delicately...), the branches of the tree come back together. The most recent example (before we escaped from there) was my great-great-great grandparents, who were first cousins. I guess that explains a lot about me. LOL.
My grandfather is from Pittsburgh but went to F&M after serving in WW2 and met my grandmother in Lancaster where she was kind of a townie and moved back to Pittsburgh (actually Scott Township / Bridgeville area). My mom left Pittsburgh and met my dad when he was in medical school at Jefferson in Philadelphia and they stayed in the eastern half of the state, so I grew up in Berks County and never really knew anything about this part of the family before.
