A number of races use a a name that doesn't match what we call them.
When I was writing my KOTOR book, I explained it as if the entire race were a scottish clan. In a Scots clan such as the Kilgour clan, you are say alex Kilgour, but the leader is the Kilgour OF Kilgour.
Since I have just read the Republic Commando books, I am going to change that since Karen Traviss has set the canon by calling their own Mando.
Good spotting. After reading your reply I went back and there were exactly twice I used it in that manner You get a Whatever prize.
