My maiden name is Keigley, but my mothers maiden name is Mangis, which originally was Mangus, but we are from Germany. Although my mother has told me that most of the Mangus/Mangis' are related. My first Ancestor in America was Johannes (John) Mangus. He came to fight in the Revolutionary War, but the first proven records started in 1779. If that sounds even remotely familiar, message me back. And if it doesn't you are still welcome to message me. Maybe we could swap some other info., and find out if we are related.
