I happen to own a drinks coaster on which is printed my name and it's meaning:

Fosters - Always cold

Oh wait... wrong coaster...

Joseph - From the Hebrew for 'he shall add' ('He' refers to God, I believe). A quiet, reserved and caring man with strong principles. He is always fair and expects the same as others.

Pretty much describes me perfectly.

As for my other names, I have refered to the internet for finding meaning:

Paul - Humble
Again, that's true. But for me to admit to being humble isn't so humble, so I'm digging a hole here.

Townsend - Pretty much what it says. My ancestor lived on the edge of a town. Maybe then he was outcast and nobody liked him.
And I do (sort of) live at the edge of a town, so I guess I am pretty much what my name describes.
