Growing up, our Louisiana great aunts always told us we were of Creole descent. They were very dark and spoke with heavy Cajun accents and we vaguely assumed they meant mixed Spanish-Cajun.
Well, we got some pictures of their mom and had our DNA done. We are Spanish-Cajun, all right, and we discovered that our great grandmother was also half black. I guess my great aunts just assumed we knew what Creole meant!
