I am rather confident that redneck white names would be similarly poorly regarded.

Can confirm. Cajun people love calling things "T'<xxx>" as shorthand for petit or little. Mostly pets/objects, but some people cross that border and name their children like that directly instead of nicknaming. The equivilant of putting "Lil Wayne" on a black kids birth certificate.

And I can promise you with anecdotal certainty not a single one ever gets above bottom totem pole in a trade for a career, mostly they are generic hoodrats hanging around trailer parks. Including the ones in my own family.
