Mine's the beginning of my first name, and my middle name. Not that creative lol

Mine is NOT from Alan Alda's character from TV's MASH, lol, its from the main character from my favorite book, Last of the Mohicans, which was also where the MASH character got his nickname from. And the 58 was the year I was born. :-)
