Re: wilhelmina (Willamina) Wirz from Germany?
My great grandmothers name was Wilhemina Wirtz. She married Joseph Paul Visner, had 12 kids and lived mostly in Rochester,NY, with stays in Minnesota and Freeport Illinois. Her mother was Hannah and
father William Wirtz, who fought in the Civil War. I am not sure if this helps with your search.Debbie
