I'm still not sure if my Schmitz's are related to this Gertrude Schmitz or not. I have her in my notes just in case. Anyways, my ancestors came from Kennfus in Prussia. Nicholas Schmitz was born in 1817 married Margaret Berres. They were both from Kennfus. He came to America in 1845 and she came to America in 1847, both to Wisconsin. Are these your relatives?
