Doesn't help too much, though, doesn't give you any real information. Woo, found my grandmother, but that doesn't help me, because it doesn't tell me what I need to go further back, unless, perhaps, I pay for it. Blah.
Ok, sure the work would also be redundant, my father's done some tracing of his side of the family, and they kicked around the midwest for a while. He's gone back a few generations past my grandmother and hasn't gotten out of the country, yet, far's I know.
