I am out of Jefferson David. He was my grandmother's father. I thank that his mother was named Arsula Williams. They may have called her Sarah. I am not sure how the McCaslins fit in,but they always lived with McCaslins. I think the whole bunch of them were very poor. Arsula/Sarah is a very elusive person. I have not ever found out one thing about her. You may contact me . My e-mail address is Jerry31847@Yahoo.com.
