Why is "ta" a popular prefix? It's just the feminine form of "your" in French. This would sound ridiculous to a French person, as all these names would. Would you call your daughter "Yourjuana"?
This is one of the most ridiculous names I've seen. Juana is not an African-American name to begin with, and I really don't get the need to shove a silly prefix to every single name. It sounds like some sort of weird article like 'the'.
