Hi. I have a copy of the Marriage & Death Notices from Pendleton (SC) Messenger 1807-1851. I purchased it recently from Amazon.com. I was researching my Pendleton ancestors, Waters, thinking I would find out about them. I now believe that the Messenger has selected entries. All this to say that it does list the Stewart death in abbrievated form and that a Robert Stewart is listed as Issue of May 25, 1838 Married on the 20th inst., by W.L. Keith, Esq., Mr. Robert steward, jun. to Miss Elizabeth, daughter of Daniel Durham, all of Pickens District. I don't know if this is your relative, but maybe? You can purchase this book, too, but I did have to wait a few weeks to have it sent to me. Good luck in your research. Fran
