In the Ancestry.com database World War II Navy, Marine Corps, and Coast Guard Casualties, 1941-1945, on page 24 for Georgia, under “Wounded,” is this entry:
“HOWARD, Charles W., Pfc, USMC. Father, Mr. David L. Howard, 104 Pine St., Thomaston.”
Looks as if your grandfather was a Marine in WWII. I don't see a WWII draft card for him in Ancestry though.
Going to the 1930 census, you find the family of David L. Howard in Cane Creek, Walker Co., GA. In the census, it's on E.D. No. 148-9, Sheet No. 2B, handwritten 4801. The family looked like this:
David L Howard 32
Gaynell Howard 28
David L Howard 11
Dorothy E Howard 9
James R Howard 6
Charles W Howard 4 5/12
Julius F Howard 1 6/12
Everyone was born in GA except father David, who was born in AL along with his parents. David was a “loom fixer” in a cotton mill (interesting). Anyway, this doesn't tell you much about your grandfather's life, but I believe this was his family.
Assuming the information above is 100% correct with out any room for error. Then I have the theory that Priscilla may have divorced Charles because charles was abusive after he become wounded. Bruce was an abusive man and that is a trate that is learned from someone else. Based on that marriage date bruce would have been 20 years old which would fit the profile. All the info I have got thus far is due to extensive research and people at genforum. My father was a lier a drunk which never talked about his mother or father.
