catching up on the story now... (don't know how i missed it before...). potter's a perfectly normal name to me. personally, i tend to think of melvin potter first, but i'm probably unique in that. i'll bet no one else here has even heard of melvin potter...
in case you're curious, he's a character from daredevil comics... he looks kind of like jesse ventura. he used to be a schizophrenic supervillain called "gladiator," who dressed up in a gladiator costume, spoke in archaic terms, and inexplicably had buzz-saws on his wrists. thing is, he always had a sense of honor, even if he was busy smashing and looting things. daredevil stopped him, got him hooked up with a good social worker, and presented him with the buisiness card of a very good defense lawyer he happened to know... matt murdoch (who just happens to be daredevil's civillian identity). matt got the judge to go easy on melvin, since (a) the poor guy was obviously not quite right in the head (b) he seemed kind of nice when he wasn't going around dressed as a gladiator and smashing things and weilding buzz-saw blades (well, okay, there's a bit more to it than that, but it's more fun this way). the social worker got him straightened out, and even ended up marrying him. he now lives a happy and productive life as the owner of a costume shop. he makes and rents custom costumes. DD has even bought a couple of spares from him on occasion.
i always thought it was a fun story.
he hasn't shown up all that much since i've been reading, but he was in a DD book i read a while back (before i started reading harry potter), and the "potter's costumes" building has made a few background cameos.
anyway, like i said... potter is a good name. it's not all that common, but it's not too uncommon, either. just like smith, it's craft-derived. that means that there are probably a bunch of potters scattered around just about anywhere, most of whom are completely unrelated to each other.
