What is Nelson Mandela's middle name and what language is it in and what does it mean?

Rolihlahla; his name was in Xhosa, meaning "stirring up trouble".

(Xhosa is a dominant language in about three dozen districts of Eastern Cape Province and adjacent Orange Free State, and in the Transkei and Ciskei. It is also spoken as a dominant language in several districts away from the main Xhosa region: in Petrusburg near Bloemfontein, and in the mining districts of Oberholzer and Westonaria, southwest of Johannesburg. Speakers of Xhosa total about 6.5 million. It is the most widely distributed African language in South Africa, although not the most spoken).

I had "troublemaker" -- same thing. Thanks again, Mr. Racer, for your answer. Hope the Cancer Society gets something out of the money that Alex won for third place.
