Sophie Brungardt was my mother's sister. They are now both deceased, as is Florian. I keep in contact with 2 of their children, Kenneth and Joan Bechard. In fact, I was the one who introduced Kenneth to his wife Berniece. They now live in the Denver area and Joan lives in Clyde, Kansas. Her husband passed away a couple of yrs ago. There is another son, Tom, but I am not aware of his whereabouts.
I found a Bonaventura Brungardt who was married to Josephine Unrein but there is no further info on them, just says that the questionaires which were sent were returned unclaimed. It does show that he was the son of Balthazar Brungardt who was married to Margaret Schamne, while my great grandfather Balthazar was married to Catherine Dreiling.
It does show that Bonaventura had 5 children, Geraldine, Wilma, Larry Francis, Janice Ann and Bonnie Joseph. Is this your family?
