I have just found this site and am thrilled.I am researching the Eisenmenger family of my husband Ed Stangl. He comes down from the Frank who is a brother of Joseph.I have a great deal of information on Frank's family. I have that Mary Eisenmenger, daughter of Peter in Butler, PA married Louis Reinhart.I think that Catherine was their daughter? I also have a book that is Descendants of George and Maria Theresia Leibfried who came to America in 1837 and 1838. I use Family Tree Maker.I will be glad to share any information that may be useful to others.
