Saw your post on Roots Web about Louisa Sizemore and her son William Thacker. I am leaving Tuesday for Ft. Cobb, Oklahoma to look at Louisa's and William's tombstones. Louisa has a daughter-in-law buried there also. I found Hiram's grave this June and his wife's (Mary Keen) in July.
They are buried in Thousandsticks, Kentucky in the woods and hard to find. They are not buried together. If anyone is interested in this family of Sizemores, I have found Hiram's sister Rebecca, brothers Pleasant, Willis, and Nelson. Also, there parents Wilborn and Sally (Jones) Sizemore. Have been working with the American Legion to get tombstones for Hiram, Pleasant, and Nelson since they were in the Civil War. Would appreciate any help with these families and the Ft. Cobb Cemetery.
