Looking for Charles Nelson and his family in the 1920 and 1930 census.

Charles was last seen in the 1910 census for Pike County, GA with his 2nd wife: Dink. (Dink Lovet married Charles Dec 2, 1909 in Pike County, GA) Living with them were Charles' children from his first wife and two of Dink's children.(The father of Dink's children is unknown as the children had the same last name as Dink before she married Charles).

I have not been about to locate Charles and Dink anywhere in the US after 1910.
