‘Blacks’ are not the only people who give their children weird names. Remember MOON UNIT ZAPPA ?
However, they do it in greater numbers.
The SOURCE (and popularity) for all the ‘african sounding’ names comes not from AFRICA, but from the movie ROOTS.
"Moon Unit" at least consists of real words. I believe she now goes by "Moon".
Her brother got the shaft; he's stuck with "Dweezil".
