Do you mean Greenville, maybe? Lotsa old money there, but it's bordering on a gorgeous area that borders Andrew Wyeth's hood. We used to do a "Valley Cruise" driving the backroads between DE and PA. I would love to live there but getting back to civilization will require some patience, and I suspect your wife doesn't have much if she wants to surround herself with entertainment and the arts. That being said, NYC is two hours away, as is DC. Philly is around 30 min depending where you live.

Hockessin is another area worth looking, and prob closer to Cecil County too, though not close enough to be a motivator for consideration.

I lived there till I was 16 and while I know a lot, a lot has changed too, and sometimes "home" is fonder in the heart than in real life.
