and then you could just post your grandpa's first name and the title of a song he taught you and your mom's cousin's song will track you down via google as happened to me last week! Granted that was a pleasant thing, but it just goes to show you that in merely talking about ourselves, we give away enough detail that a motivated person can find us.

My Cousin musta been googling on some song names and first names or.. town names since I included that and up popped my mudcat post!
