This is a pretty complicated issue for me.
On my Dad's side, it's English and Powhatten indian (his great grandmother was full blooded Powhatten). Since the English family line has, through genetic testing, been traced all the way back to various noridc peoples, this results in lots of blonde hair and blue eyes in the family. Throw in a little Native American, though, and you start getting combinations like my dad: extremely dark skin, dark hair, and blue eues. But anyway, that's all clear cut.
My mom's side....that's another issue.
Except for not having mixed race*, my Mom's side of the family fits every single definition of Creole there is. French speaking (my Great grandfather didn't speak a word of English until he was 13 years old) Catholics from a heavily Creole part of the state, all the family names and surnames are unquestionably French, but French names found more in Creole areas than in Cajun areas, all the family recipes are Creole cuisine, etc. Basically any identifier used to designate someone a Creole in the state applies to my Mom's side of the family, except the fact that everyone is white.
So what does that mean? The geneology is lacking, but I've always maintained that we broke off from a tradiaitonal creole family at some point. With all the intermarrying, affairs, and what not at the time it seems the most likely explanation.
* There's still a whole debate over what "creole" actually means. The original definition was someone that was born in the Louisiana colony, but over time it's grown to reflect a pretty specific cultural foundation found with people of mixed racial ancestry. That's the definition I'm using.
