Edward and Blanche Hands

Looking for info on Edward Hands Sr. (1893-1979) and his wife Blanche E. Hands (1893-1956)
They had a daughter Dorothy May Hands Gregory (1913 - 1938) They are all buried in the Justice Cemetary in Oxford Indiana (Benton County). This is all I have. Dorothy was killed in a car accident and another family member raised her three children. There are rumors that there is Native American Ancestry. Any information at all will be appreciated!
