How should I choose a suburb in Roswell, Atlanta?

Hi there, My husband may have opportunity to move to a job in Roswell, Atlanta (leaving the UK). From reading this forum it seems sensible to move to Roswell or a suburb nearby given the traffic. Which areas are best for schools but also community? Coming from the UK I am a little worried about living too remotely or living in very quiet sprawling suburbs. We currently live commuting distance to London in a busy but green suburb, so we have the best of both worlds. In terms of priority it would be elementary schools, having a reasonably sized garden and being part of a friendly and busy community near to open spaces. Oh, and of course somewhere safe. Any suggestions? Many thanks.
