Hello group, Today in the mail I receive a copy of my great grandparents marriage certificate. My great grandfather, Vincent Birkhoff, lists his parents as Cornelius Birkhoff and Katie Roetman. I am looking for any information on the Roetman family, especially Katie. Vincent was married 06/19/1907 and was 27 (born 1880), so his parents would have been married about 1875-1879. Thanks, Vern Ferguson Roanoke, VA
