Hi Ed, there's a bunch of us cousins working the family line of Umback, Spitzer, Schoenberg, and Krebsbach, families. I descend through Mary Ellen Umback and Edwin Spitzer, I've talked with Sheila Guvakosky in minot nd, she has some info on the Krebsbach line as well. Hope your still here and doing the research, we can help you.
