Hello and nice to hear from you. I see that Francis (Franz in Germany) Reibel is the son of William and Mary Reibel. I don't see a son by the name of Alphonsus, however my data may be incomplete. I show that Francis Reibel and Christina "Annie" Hoffman had 6 kids (but there may be more). If your grandfather is the son of this Francis, he would be the first cousin of my grandmother (who was the daughter of Francis' younger brother Bernard). I show that Francis died on May 21, 1920 from choking on a piece of meat.
