By 1836, "Rock" Jackson had migrated to Chambers County with his wife Martha Foster Jackson (1810-1849). His primary business was the manufacture of tombstones and jugware.
His "tested blue marble" tombstones as he advertised, can be found in cemeteries throughout Chambers County and adjacent counties in east central Alabama and west Georgia. They are easily recognized by their greenish-blue colour; the stone has been identified as green schist. His quarry was located west of Penton, south of Milltown, and just south of Sandy Creek that flowed through his property.
