Joan Crawford
Oh yeah, I got tons of ideas for rich last names:

Winchester
Van De Kamp ((if you're a Desperate Housewives fan))
Gordon
Dubois
Baldwin
Carrington
Sachs
Corsetty ((if you're going for an "Italian Mob" theme))
Crawford

HEY!! I have a friend whose last name is Crawford, and they're pretty well-to-do. Actually I think his dad owns an Ford/Lincoln/Mercury car dealership... go figure. xd
And the Italian Mob family thing is actually a good idea! Could also use names like Zambini, and just watch The God Father, Goodfellas, Casino and films of the like to get name ideas for the Mob theme.

And on to the neighborhood thing, it's pretty funny because either we(as me and my sister) either made our gigantic houses or downloaded the mansions off the website. So the beach area of Pleasantview has all the rich upperclass looking houses and the other side of town has the mobile homes and shacks. xd
Very realistic from what I see today in most communities. 3nodding 3nodding
