I am looking for any information on my grandfather, Robert Siford b. 2/10/1915 d.3/1982 in Phoenix, Az. He married Jane Traver. They had two sons, Robert (Butch) Siford b. ? and Jack G. Siford(my father) b.1/16/1946. Both sons were born and raised in Indiana. Grandfather moved to Phoenix sometime during/after my fathers high school years. Any information on his siblings/parents appreciated.
