Benjamin Adams & Caroline Culpepper of Heard Co., GA

I am looking for the parents of Benjamin Adams, b. Dec. 20, 1822 in South Carolina and d. May 21, 1894 in Heard County, Georgia. He married Caroline Culpepper b. 1835 d. 1921.
Their children were:
Mary Adams b. 1854

James Kinard Adams b. April 9, 1864 d. March 15, 1926
Brenard R. Adams b. 1865 d. 1933
Emma Adams b. 1867
Daniel Adams b. 1869
Millie Adams b. 1871
Madison Adams b. 1874
Emily Adams b. 1875
Mack F. Adams b. December 11, 1877 d. April 24, 1950

Any help on this family in either direction will be much appreciated.
