OK ... so, I'm not a big Tolkien fan (I didn't get the "Barrow-Downs" reference when a friend sent me this link) ... but I went and plugged in my name to see what it was in that context (oh, it's here ... http://www.barrowdowns.com/NameGen.asp ... I won't try to explain) ... I came up with "Lonely Ruffian", which somehow seems appropriate.
