Jean, My father's father was Edward Youngberg and I'm awaiting a copy of a SS card app that will tell me(hopefully) HIS father's name. Did you ever hear of the Swedish derivation of Youngberg? I've been told it was(among others) Ljungberg, I think. Did your mother have any relatives in MN? By the way, I've also started to research my father's mother's side. Her last name was Gaul. Anyhow, I'll keep trying.
