Steve, in other areas on the Gulf Coast, Creole included people with, what they considered a small amount I guess, Negro blood. It wasn't quite a dating mecca or a romantic metropolis in the early days with the Spanish and French. I think it may have been a bit stodgier when the British were in command but especially the Spanish had no qualms about ignoring social rules if they didn't like them. Some would say they were arrogant and I'd have to agree. I mean, like when Andy Jackson showed up to get the 'keys' to the Kingdom here, the Governor wasn't 'inclined' to receive him at that time. Andy waited a bit and then he got impatient and had the governor tossed into the calabosa. The same jail that was falling down because that same governor wouldn't bother to have it repaired. Others who had been incarcerated just walked out of it but I guess the Gov. got the message and turned over the keys.
I have a paper somewhere someone wrote years ago on the componants to the Creole Society around here. I'll dig it up and post what it says. They were the ones who began Mardi Gras here in Pensacola.
Later it was different. I do not know just when the rules changed but in the very early days of the settlement, it did include Negro blood. Not well advertised and mostly not recognized by marriage but just the same, that's what it was. Matter of fact, I don't know just who made the rules on it back then. In La with the Acadian presence, it was a different mix. In La there were levels in the social tier that included the Quadroons, Octoroons and they held to their status among each other. Much more structured social setting than here.
So I'd believe the Creole Guards from La had less to no chance of having Negro than say Creole Guards from Pensacola or Mobile.
