Mine is a pseudonym I use when registering software that I suspect will deluge me with spam. Also my real name was already in use on gmail.
There was an old western on and there was this old trapper/ mountain man character called Jedadiah (Son called Jed, Mountain Man called Jedadiah) This character seemed wise yet not arrogant, confident not bullish and just seemed to be the type of guy i'd like to spend time with (don't read anymore into that than is meant)
I got my username from mummy and daddy in 1951. It's kind of stuck with me ever since.

Because its easy to spell
Mine came from a character from a series of books called the executioner, the main character is called Mack Bolan and his call sign is StonymanOne, I'm a big fan of the books and have used Stonyman as my username for a while, my avatar is the man himself Mack Bolan.
I think it's the name of a bomb developped by the us army also... it was baptized Mother Of All Bombs
