Mine's the middle name of my 3xg grandad. I've never been able to find out where the name came from and it's always puzzled me. I'm assuming that because (I think) he was illegitimate, that it could be the surname of his father, but I've not been able to prove this or even find any clue that this is the case, it's just speculation.
I don't know why I kept it all in lower case - just a whim - but now I wish I'd given it a capital W, so I often do when I'm signing off.
