Sandra, John J. Black, Sr., b. ca. 1776 was son of William W. Black, Sr. (b. ca. 1753) and Elizabeth Jane Tumblin (b. c. 1755).
John J. Black, Sr. had children:1.Abian Black, b. ca. 1796. I know nothing about this man, apparently he was deceased or moved away by 1826 when his father died since no mention or provision was made for him in distribution of his father's assets.2.Isabella Ann Black (b. ca. 1798), married Thomas Marler/Marlow. I have not been able to find anything at all on this couple.It is possible they moved away from Georgia. 3.William A. Black (b. ca. 1800), married 25 Dec 1825 in Decatur co, GA, Edith Eady Rodgers.4.Douglas A. Black (b. ca. 1803), married Anna.5. Neyland Black (b. ca. 1805) married 3 Nov 1836 in Decatur co, GA, Nancy Carver.6.Jane Black (b. ca. 1808), married 24 Sep 1827 in Screven County, John Connor (Jane and John Connor moved shortly after they married, first to Illinois, then finally settled in Independence County, Arkansas.
