I have found on many online Grafton trees a Thomas M Grafton Jr b abt 1750 or 1752 d Sep 1798 Fairfield District SC. I have headstone proof that Thomas Grafton Jr [no M.] is buried at Mt Olivet Cemetery d 14 September 1798 age 56 years old. Next to him is Mary Grafton d 1827 age 71. Also in the row is Thomas Grafton d 1797 and Elizabeth Grafton d 1798.

Where did the initial M come from?
