I am the great great grandaughter of John Jermann and Mary Catherine Wilde. In addition the the children previously mentioned, they had another son, Aloysius, born 1878. He was my grandfather. When my father Aloys passed away, my brother inherited the family paperwork. If I recall from the paperwork, her middle name was Catherine. I believe from the paper work that John's father was Meinrad Jermann or something similiar.
