I believe your great grandmother is also mine. Our records show Mary married Thomas Dykes and had a son James Alford Dykes. Her tombstone at the Williams Buck Cemetary shows her name at the time of her death as Mary Pulliam, born Apr. 18, 1820 and death March 3 1898.
If this isnt the same peraon I apologize. While i have a very long background on my grandmother's side of the tree, i do not on my grandfather's side. I was hoping you may have some insight.
