Don't know if this is right track or not, but found mary J Grubbs, Widow, living with her father Benjamin Grubbs. It would not be unusual for him to call his DIL , daughter. With her children John and Deller (Della?) Grubbs. Benjamin Grubbs had a son John named John b 1840 and a son named David. No indication of being Choctaw, that I could find.
