According to his WWII Draft Card, Edward's birth place was Missouri. I believe this may be him with parents in 1900.
Father, Isaac Ingram and mother, Sarah P. Slover (according to their marriage record)
And I do see this family in Oklahoma after 1900.
I will post what I found on his wife's parents separately.
