The only Charles and Betty I find on the 1910 Census in Kirby, Northampton, North Carolina does not match the birth years in your posting.
1910 Census Kirby Northampton, North Carolina
Charles Futrell, age 25, born about 1885 North Carolina, Black
Wife: Bettie, age 21, born about 1889 North Carolina, Black
Is the Charles Thomas Futrell (1876-1972) I found the Charles you are looking for or not?
It would be helpful if you could post the census information you found with your inquiry so that those who wish to help you don't have to research what you have already found.
