OR somewhere in rural essex, maybe? Thats where i live, and my dad commutes. It takes about 40 minutes or so. Try somewhere like Rayleigh (Not so rural, i guesss, but still) or Rawreth, perhaps. And for Essex, you probably would be able to have the dad working in a factory too...theres a big Ford place down here, and lots of other stuff too.
Or how about Norfolk? I believe it's about an hour and a half....
Edit: I should probably add here that these times are to commute to London
