Also, Maria Louisa Jefferson Mullies died in 1900 and is buried in Woodfin Cem., near Foster, Mo. in Bates Co. Her husband, Thomas, died in Cofederate Hospital in Richmond, Va. in Dec., 1863. His widow traveled by ox cart to retrieve his body and return it for burial in Hendren-Mullis Cem., a family cemetery, off Trails End Road in Wilkes Co., N. C. In 1982 I arranged for a military headstone for Thomas Mullis Mullies (sic), the only engraved, named marker in the cemetery (about 40 plain stones total).
