Merged: surname meanings

Cześć
Could anyone tell me the meaning of the surname Olczyk.
I've heard a few explanations, one was that there's a small town in Poland called Ol, so the meaning could be literally son of Ol and was possibly a name given to someone who did something notable for that place. Can anyone elaborate on the meaning of this name.

Many thanks
Dziękuję
