My ggg-grandfather was William Callas (Kellis) from Oconee Co., SC. He married a Lucy Morgan. Although I do not know for sure what William's father's name was, I believe it to be James. William was born about 1812 in SC. His children: John, William, Eliza, James, Harriett, Josiah, Jasper (my gg-grandfather), Newton, Ara, Matlida.
Looking for other family members to compile notes with.
