As noted, the Clements brothers were in Pendleton District of South Carolina in the 1790s living just south of present day Williamston. They left Pendleton District and moved to the new frontier of Jackson County Georgia. Charles appears in the early tax digests. Jackson County's western boundary was the edge of the vast Indian lands which were shortly to become bona-fide counties of the State of Georgia through various treaties.
In December 1818, the land in the Hog Mountain area where Culliver lived became split into Hall, Gwinnett and Jackson Counties. The early land records are available for Hall and Jackson Counties but due to the Gwinnett Courthouse fire (deliberately set by some knuckleheads) in 1871, most of the land records for the early years of Gwinnett are lost forever.
Culliver likely lived close to present day Interstate 85 and Highway 60. He is shown to have been a charter member of the Walnut Fork Baptist Church in 1802 and he was one the church's first deacons. This church is still in existence today and located on the same land that is on Highway 60. Other Clements names shown to be founding members are Agnes and Joanna, presumably one of these women is his wife and the other is his daughter. [1]
Culliver is noted by other researchers to have moved to Alabama about 1818 where he died about 1840 or 1843, buried near Ethelsville, Pickens County. He was shown as a tax defaulter in Jackson County for 1808 but he is listed on the 1810 tax digest. Later years' tax digests are limited in clarity. Alabama was not officially a state until 1819 so he likely was living in one of the western counties of Georgia (Fayette or Carroll?) for some years (he is not listed on the 1810 or 1820 censuses). In the book "History of Pickens County Alabama" by Nelson F. Smith, Culliver arrived in Alabama in 1818. The book also claims that Culliver was a Revolutionary Soldier while in South Carolina (no details provided however). He is listed by other researchers as having served under Colonel Thomas Brandon in the Spartan Regiment and having participated in the Battle of Ninety Six. Again, I have seen no documents confirming his Revolutionary War service. The Alabama Archives does list Culliver as a Patriot soldier; However, the information seems to have been based on the book by Nelson F. Smith and Smith's short biography of Culliver is a little ambiguous based on what is now known about these Clements men. Update: Culliver Clements is listed as a Partisan Soldier in the Roster of Patriot Soldiers at the Battle of Ninety Six on the National Parks Service website but again, no documents or available sources are noted.
In the plat records for William Clements, there is also a plat listed for Culliver Clements (William's uncle). It does not appear that their lands adjoined so the plat entry may just have been an alphabetical recording.
