I was so suprised to see someone wanting this information I called my Mother who was in bed to get more information. My Mother is Marguerite Hartzog Metcalf who is your Grandfather's sister. The only thing she could tell me tonight was that her Father was Henry Goerge Hartzg & her mother was Carrie Viola Chance. She did say that her Dad did have a brother named Ike Hartzog who lived in Helena Montona and that he did have a sister. She did say she would look in her family bible tomorrow and see what else she could come up with. I do remember your Grandfater who was my Uncle George and his wife Aunt Agnes. You say he died in 1975 I was 15 and not really interested in family at that age but now that I am older I am. I will send you more info when I get it and like I said i was suprised and axcited to see someone interested.
