Thanx for your reply. Information that I have says that Carl Hemmann, who was the brother of my ggf was b @1852, d. after 1922. Not ruling out a connection. Are you confident in the data you have? Do you know any more from census data than birtha and death like addresses? You said that Carl R was born in Ny and Carl was born in Germany? Do you know what pert of what is now Germany?
