Hello. I'm trying to get details on my grandfather's line. Ira Eugene Hartwell was born in 1927 in Sprinfield, MO. Died in 1972. He married Floy Carmack(?) and they had four sons - Ira Randall (my father, born Barstow, CA 1947), Ira Dale (died 2000), Ira Matthew (who was a twin(?) - twin died in infancy).
