Nicholson's graveyard

My 3rd Great Grandmother was Rebecca Paulk and she married James Hogan on August 14, 1834 in Stewart County Georgia. Her marriage record was one of the first things I found when I started researching the Hogan family about 15 years ago.

It was several years later that I found a record that James Hogan had a second wife. James died in 1879 and his widow, Melody Arnold Hogan filed for a pension, claiming he served in the Creek Indian Wars from 1836 to 1838. As part of the application she filed an affidavit that Rebecca had died on October 4, 1847 and was buried in Nicholson's graveyard in Stewart County Georgia. It would have been 162 years ago this month.

I've looked for some reference to this cemetery ever since without success. There are several publications listing the cemeteries in Stewart and surrounding counties but none have one called Nicholson's. It would be nice to be able to locate it and see if her grave is there. Maybe one day.
