I do. My mom's side is fairly easy, as the family stayed together, but on my dad's side, he never met his father while he was old enough to remember, and his parents separated before he was born, and his father went wandering, leaving a trail of IOUs and bad checks. I don't know all the jails he was in (Washington Co., PA was one of them, and my dad thought maybe in Baltimore, MD also), and he eventually died while riding a bus in Columbus, OH. He was spared a pauper's grave by being friends with the owner of a funeral home, who did the services free. Anyway, I'm having a tough time getting any information. I do have a membership on ancestry.com, and that at least gives me copies of census documents to look through.
I hope you are having better luck than me.
