I have some Barrineaus in my family as well. I do not know of a Caroline, but I have a Marie Lequia Barrineau born 14 Mar 1902. Her father was William R Barrineau born 1868
Williamsburg County, South Carolina and Died 7 Aug 1918
Charleston, South Carolina.

Unfortuntly, I don't have any more information on this line of my family.
