Have you checked Heineggs book online? - A James and Mary Shoemaker are listed as taxables in Granville County NC in 1762.

Also Botetourt county went through many shifts and changes over time - you might want to check surrounding areas.

Who did Mary Ann (the daughter) marry?

Do you have any idea if the surname Shoemaker/Shumaker was an occupational surname or if at some point they were owned by a Shoemaker surnamed family?

Have you discovered any records of emancipation?

Do you have census data for them after crossing over to become white?
