I have your Martha listed as a child of William Blume (b. abt. 1790, d. 1860) brother of Darling Blume, who also had a daughter named Mary Ann. I do not have a positive date of birth for William's Martha, only some time prior to 1846, as that was the year that William's wife, Mary Birt, died. William was the son of John Blume, (d. 1816) and his wife, Sarah. I have not personally researched this information and cannot give you positive documentation details. Mary Ann is buried in the Blackville, SC. Cemetery. See Cemeteries, Blackville, Barnwell County website on US Genweb.
Why did they all use the same names for their children? Just to confuse us even more?
