There are a number of Austin Fowlkes. I recently located the marriage bond for this one so thought I would eleminate this one for others.
Austin S.(Sterling) Fowlkes b. aft. 1810 in Nottoway County; a son of John Sterling Fowlkes and Elizabeth Jennings married 11-20-1837 in Prince Edward County, VA to Martha Ann Frances Armes b. abt. 1816 in Prince Edward County and died after 1880 at Manchester, Richmond, VA at the home of her son Patrick Henry Fowlkes and Mary Elizabeth Harper Fowlkes. She is a daughter of William Armes and Mary W. Forrest.
They may have had only one son: Patrick Henry Fowlkes.
I have considerable documentation on this family if this is of interest to anyone doing research.
