Interesting, Uhura is probably a European with an African name; or a bi-racial Euro-African with very prominant Caucasian features...or a woman who hailed from Africa and had an African name passed down from generation to generation...i.e. a different version of Charlize Theron.
Actually "Uhura" isn't a real African surname, but a coinage created by adding a Latin feminine suffix to the Swahili word uhuru. So it's not pinned to a particular ethnicity, and indeed it smacks of European influence. It could've been that this rather Nordic-looking woman's ancestors simply chose to change their family name to something inspired by a Swahili word. (Or she married into a family that did.)
....And 'Sulu' is now an Afro-Asian....
You don't even need the Asian part. Sulu is actually a valid Nigerian personal name. At least, there's an Emir of Nigeria named Ibrahim Sulu-Gambari. (And as far as I can tell, it isn't a valid Asian personal name. It's the name of a sea and a province in the Philippines, but I can't find any indication of its use as a personal name there. And it sure as hell isn't a Japanese name.)
