Ashley, I realize you left this message years ago, but we are pretty closely related! Every name you mentioned in your chronology matches mine, right up to Homer, who was my Great Grandma (Helen's) brother. I am also related to the Linthicums through Lilly, and the Blalocks through Charles F.
Makes us cousins, no? :)
The Linthicums are the only line I've been able to trace, so if you have more info on the Blalocks, I'd love it!
