Mr. Marshall, My family records show that a Philip Vincent Vass (1720-1768) was the oldest son of John Vass(1690-1754) and Rachael Pendleton. He married Mary Curtis, daughter of Colonel Rice Curtis of Spotsylvania Co. He like his father John and his grandfather Vincent Vass (1620-1727) was a plantation owner. His brother John Jr. served in the Revolutionary War.He had four boys and two girls. His oldest son John died childless and myancestor Rice Curtis Vass (1755-1820) inherited the estate.
