My great-grandmother was Catherine Gaug and she married John Robert Koschel. She came over to the US from Austria-Hungary as a child around 1906. Her parents were Peter Gaug and Margaret Kurtshalts and I know that she had about 7 siblings. She was born in 1896.
I have no idea if our Gaug's are connected since you are so much further back in time - but it would be nice to find out more about the Gaug's!
