Dave, my name is Theodore (Ted) Prahl and I live in nwest Fl. My father was Theodore, born 1904 in Chicago. His borthers and sistes: Fred, Johanna, Walter, and Martha. I take it your grandpa was Walter, his son (my cousin) was David, whom I presume was your father. My email is prahlclan@speedeenet,com, phone is 850 537-3472. If you're still doing family research, email or call, I might be able to help.
