One James W. Caro was the son of Phillip Antony Caro and Mary Ann Weaver Caro. He married Clara de Rochblave. They lived in the Octogan House on what is now NAS Pensacola. I think it's the legal affairs building now.
His father was a brother of my 3x GGrandfather (The Keeper).
The other James W. Caro was the son of Joseph Estevan Caro (The Keeper) and he married Minnie Daniels.
