There was a Jacob Fitzhugh and a John Fonteroy (in separate households) in the tax list for Petersburg in 1832.
I imagine Fonteroy is actually Fauntleroy. A W. Fauntleroy freed someone named Roger in Richmond County before 1797 and there was a Judith Fauntleroy who was counted as a free Negro in Richmond County in 1813. (Many tax commissioners mistakenly listed free African American women in 1813).
I also noticed a D. Fauntleroy who was head of a Lancaster County, Va. household of 2 "other free" and 2 slaves in 1810.
