If I’m not mistaken (and I rarely am) thw “X” in the first name represents a “click” sound, used as a vowel in the Niger-Bantu languages of the Xhosa tribes.
It’s the same group from whence Africa got such cultural icons as Miriam Makeba and Winnie Mandela.
Mariam Makeba is a cultural icon. Winnie Mandela is a political leech on her ex-husband and an instigator of necklacing. Which apparently is not as bad as waterboarding.
