I Am Looking for the Ancestors of Thomas Dunkinson Born 1763 Spotslyvania County Virginia

After some research, I believe THOMAS DUNKINSON is an ancestor of mine...I claim this as I have a documented Ancestor, WILLIAM DUNCANSON b. 1726 Scotland. "Transported" to Colonial Virginia 1740. He escaped servitude into the backwoods of Spotslyvania County VA. 1746.
