My name is Don Beard, and I have done some research on the Vanover side of my family. All of the people in your listing are direct ancestors of my grandmother, Mamye Louise Vanover (Beard). I am tickled to find this link. If you would be interested, I have pictures of Vanover tombstones from Brushy Fork Cemetery. Of particular interest might be Henry & Martha, and Samuel & Rebecca.
Please let me know if you need anything. I look forward to hearing from you.
