I don't know anything about Louisiana antebellum law, but having been born and raised and lived most of my life in Louisiana, I know considerable about the social situation in this state. And I know that being Creole has nothing to do with having Negro blood. In early Louisiana, the white population basically consisted of "Creoles," "Cajuns," (or Acadians) and "Americans." The colored population consisted of pure Negroes, and people with a mix of black and white blood, the white blood being either Creole, Cajun or American. So while it is possible, and quite common, for mulattoes to be Creoles, a mulatto is not necessarily a Creole. The term Creole, until bastardized for whatever reason, has nothing to do with black blood. The correct term for a person of mixed Negro and Caucasian blood is mulatto. Apparently, some people shy away from that term for politically correct reasons. I have never understood why someone would be so ashamed of who they are that they would want to disguise that fact behind semantics, but it seems that some people are. Sad.
