Well i just wanted to add my name to this list :-p
Fengor dates from my early role-playing days. Since most of my experience in that region was from Tolkien books at these days i used them to create a character name for me. But i didn't want to just simply take a name out of the book (a bad habit of many new role players ;-) so i made a name up by combining two other names. Namely: Feanor and Fingon.
These are two very different charcters and over the years fengor inherited some of both into his character.
This was how i came up with the name fengor, who is btw one of my oldest and most liked characters :-)
