Per information found at:
"The first to settle in the area that became Rockdale County was William Mitchell (1777-1859). William, the father of Isaac G. Mitchell, moved in 1834 or 1835 to a farm on South River, below Flat Shoals, or Panola, in Henry, now Rockdale County about 12 miles southeast of Decatur, Georgia. He and his son, Isaac G. Mitchell in additon to some other members of the family, are buried in a family cemetery on this farm. Much of the land is now part of Little Mountain Golf Course. There is a subdivision with houses on a street which runs by the cemetery. This cemetery lies in Rockdale County very close to the Henry County line within sight of Panola Mountain. It is on record as the Mitchell Cemetery. There are only three marked graves. The others are in unmarked graves."
