We think that your Ga. Cornelius is the son of our SC Cornelius. Cornelius moved to Paulding Co., Ga and so did Howard Barbare who would have been my ggggreatuncle. We know the families knew each other because Benjamin Barbare, the father of Howard, owed our SC Cornelius $6.00 when he died according to the probate papers. Robert moved to Ga. with his brother but he moved back to SC. A lot of the families from Greenville, SC moved to Ga.
Keep in touch and maybe we can find a link to the mystery.
