Not everyone is interested in genealogy, that's up to them, but to those of us who are, finding an unknown nth cousin may be worth a lot to untangle the lives of our ancestors, write the stories of our families, and find out where we come from, in a far wider sense than merely the genetic one.

But Ancestry is a roach motel. Of all sites that sell user-contributed data back to their users, and they're all scummy, I don't know any which are more scummy than Ancestry and MyHeritage.
