Many of us have surnames which are the result of what others called one of our ancestorss. My surname originated in Cornwall and is the Cornish for "broad browed". SWMBO reckons the more accurate translation would have been "big headed" : can't think why. Our son, who lives in a small Spanish mountain village, says that everyone has a nickname which everyone knows, apart from the person on whom it is bestowed. A local mayor had the bright idea of publishing a village directory under nicknames instead of proper names, thus everyone found out what the rest of the village called them. The mayor had to leave town and change all his names. As for Native American names- I can thoroughly recommend the Autobiography of Left Handed, Son of Old Man Hat (ISBN0-8032-7958-2) published by University of Nebraska Press (Bison Press 1995) Left Handed was born in 1868 and his book gives a facinating account of Navajo life, including naming systems.
