Christine,
I really wish I could help you out, but unfortunately I seem to be hitting a brick wall in regards to my father-in-law's side of the family.
I do know Ted's SS number was issued in Massachusetts, but beyond that we know nothing about the Sowa line except that he has a daughter Cindy somewhere by a previous marriage.
I won't swear to it, but I don't think there is a Minnesota connection, but if I find one, I'll let you know.
