Becky,Yes, I have a copy of the picture of Thomas Buford Johnston and will be glad to send it to you. If you will email me directly at email@example.com I can attach a .jpg file of the picture and send it to you, or you can provide me with a postal address and I can mail one to you.
Some years ago I corresponded with the wife of a cousin in your branch. He was Buford Waller, descended from Willis Wheat Waller, son of Sarah Ann Johnston and William Edmund Waller. It was through her that I gained knowledge of the Goodloe Family Bible and the Waller Family Prayer Book being passed down through antoher branch of the Johnston family in Mississippi. She provided me with a transciption of the notations in the Bible family pages and they proved to be very helpful in sorting out who was the granfather of our Thomas Buford Johnston.
