Robert Oglesby b.1826 Tenn or Al d. Miss

I am looking for the parents of Robert Daniel Oglesby. I don't have a lot of info. on Robert. The first record I have of him is the 1860 census of Choctaw County Miss. it states that Robert was 34,born in Tenn.,married to Caroline A. age 29 born in Miss.,and had the following children:
Walter B. Oglesby age 8
Coleman F. Oglesby age 7
William H. Oglesby age 3
Mary B. Oglesby age 2
The 1870 census of Choctaw County Miss. show Robert and Caroline with all of the children
above(Coleman is listed as Calvin in this census) plus these 4:
Amanda Oglesby age 10
Sallie Oglesby age 8
Martha Oglesby age 2
John Oglesby age 3 months (John was my great-great-grandfather).
The 1880 census of Sumner County Miss.list C.A. Oglesby(born in Miss.and both of her parents born in S.C.) with the following children:
Manda age 20
Sallie B. age 18
John R. age 10
They were living with W.D. and Mollie Evans.

I think that Robert must have died between 1870 and 1880 because I can find no farther records of him after 1870.

On the funeral record for John R. Oglesby it states that his parents were Robert Daniel Oglesby(born in AL) and Caroline A Roberts(born in Miss.).

If anyone has any info. that they think could help please respond.
Thank you!
