I believe that you have the right John R. Sims. Some of his children with Rebecca was Roy, Johnny,and my grandfather Jake. Also I believe that there was another brother with Rebecca. They had some girls as well. After Rebecca died somewhere late 1910 or early 1911. Later he married Nancy and had more children. Some of the girls were Hattie, Hester I think, also one boy that I remember was Carl. I am sorry that I don't have all the names right now. Hope to hear from you soon.
