I am told Mrs. Musgrove is buried in Chelsea, Oklahoma in a family plot. She married William A. Musgrove (buried nearby) in 1844 after her first husband, Robert Rogers, died. She and Robert had two children: Margaret Lavinia and Clement Vann--father to Will Rogers. It is with the Rogers family that she is buried. Sallie was of the Wolf Clan of the Cherokee Tribe.
