Where African American first names come from?

by catch-a-stream

So, my understanding is that until about WW2 time frame, African American first names were mainly European based... your typical Georges, Michaels, Martins etc. But then at some point this has changed... because now a lot of the African American names seem to be completely invented ... LeBron James, Selena Williams, Ha'Sean "Ha Ha" Treshon Clinton-Dix and so on. Where these came from, how and why? Is it purely American cultural thing, or is there a wider world-wide theme for this?

Hopefully this question is allowed by rules but please let me know otherwise.
