I'm pretty sure she does have a birth certificate. I just haven't talked to her much about her family, but I will when I see her next. I grew up with my father, so all I know is what I've heard in bits and pieces over my lifetime and the very few occasions that I've actually met my Ohio relatives (mostly when I was a kid). But I'd like to know more.
My grandfather was supposedly a legendary scoundrel who spread his seed far and wide, if you know what I mean. Again, that's just one of those fragments of the story I may have overheard once when I was 10 years old that I filed away in my mind.
Her first and middle names are LInda Lou. Her brother's name is Geraldine (I think that's how it's spelled, but couldn't swear to it) and her other brother (who is most likely a half brother, maybe not a brother at all) is named Gary. Both of the "brothers" are older, and all the siblings are still alive (well, at least, last I heard).
