Looking for information on a Carl Ruebenack who went to possibly San Francisco, Ca. during WW1. He left Seattle, Wa and supposedly moved to San Francisco. He was my greatgrandfather. Last known in Seattle about 1916. He was born in Germany. He may have changed the spelling of the last name, or may have changed his first name. Supposed went by Charles at times. He left behind a wife and four children at that time. My grandmother was one of those children. He was born about 1867.
