Seeking info on Peter Oglesby, Sally Pratt and children Robert W.; Thomas; and possible daughter Jane.

Peter Oglesby m. Sally Pratt in Amherst Co., VA, 16 Jun 1800.
Peter b. 1771-1780, d. after 1830.
Sally b. 1771-1780, d. after 1870.

I believe them to be the parents of Robert W. Oglesby (b. 1804 VA) and Thomas Oglesby (b. 1807 VA).

Peter is listed as head of household in the 1830 federal census Knox Co., TN.

Parents and their two sons lived in Knox Co. for the remainder of their lives.

I am descended from these Knox County residents:
Robert W. Oglesby m. (1st m. Elizabeth Pratt, 2nd m. Abigail Reed) >>>
Wiley Hazen Oglesby m. Malissa J. Cash >>>
Isaac Newton Oglesby m. Laura Mae Pickle >>>
Homer Alexander Oglesby 2nd m. Beulah Frances Reed

Any info that you might have on birth or parents of Peter, Sally, and family link to Thomas, Robert W. or Jane would be greatly appreciated.

Thanks,

David
