From the experts:
A saucy showgirl, wisecracking waitress kind of name, Dixie can also be considered a place name, although it won't be found on any map, being a generic term for the whole American South (coming from either the ten-dollar bills used in French-speaking New Orleans, which came to be called dixies, or else from the Mason-Dixon line). Dixie, which had been as high as Number 167 in the late 1930s, jumped back onto the popularity list in 2007.
Dixie Carter was a TV actress best known for playing Julia Sugarbaker in the sitcom Designing Women, and the name is also associated with the country music band The Dixie Chicks.
Kings of Leon frontman Caleb Followill and wife Lily Aldridge named their daughter Dixie Pearl in 2012.
