Mary Ridgway was the youngest of seven children. She married Levi Stinchcomb, son of Absolom and Sarah Stinchcomb, on July 27, 1806. Source of this information is Ridgways in the USA. by Gertrude n. Brick and Thurman Ridgway, Gateway Press, Baltimore, MD, 1980, p. 517.

I presume that you know that Lucy Christian was a daughter of Robert and Lucy (Bradley) Christian of Albemarle/Amherst Counties, VA.

I have estimated Lucy's birthyear to be about 1746, and her marriage to Thomas Ridgway circa 1768. Thomas died in July 1801. What do you know about their family unit?
