Kathy-Lynn, The bro of my Margaret (CARROLL) LAMB, James CARROLL, was Margaret's full brother, b 1801 - d 1869. James was born in Duplin Co, NC, son of John CARROLL 1770-1826 & 1st wife, Elizabeth (HOLLINGSWORTH). James & sister Margaret were the only 2 children on record -1st wife Elizabeth (HOLLINGSWORTH) CARROLL, must have died either when James was born or shortly thereafter, as John CARROLL then mar 2nd, Ann "Nancy" (HOLLINGSWORTH), the sister of his 1st wife, Elizabeth.
James CARROLL 1801 NC-1869 GA, came down into GA in the late 1840's along w/sister, Margaret & her husb, William LAMB & their half bro, Jesse CARROLL, his wife & children.
This James CARROLL was mar twice: 1st w, Elizabeth was the dau of Thomas CARROLL, bro of said John CARROLL. These were mar 24 July 1822, Duplin Co, NC.
After 1st wife's death, James CARROLL then mar Mrs. Sophronia E. RANEAU of Thomasville, Thomas Co, GA.
According to Huxford's info, there were 11 children from the first marriage, but only 1 from the 2nd.
James (1801-1869)had a son James Henry CARROLL from 1st marriage b 1827,mar Catherine Huffam of NC. But their son also came down to GA w/the others in late 1840's & d in GA according to Huxford.
I do not see a son named James from their half-bro, Jesse CARROLL 1803-1883 & wife, Margaret (CHESNUTT). As stated, they also came down to GA & died there.
