I'm in CT , and agree with alot of what John says above.
Wilhendorf is not my cup of tea and I'd be glad to tell you why if you want to pm me.
Have you got any german shepherd experience? They can be tough very bitey puppies especially if you have young kids..they don't call them sharks for nothing
With that, the only two in CT that I would refer you to, are Von Monte Haus in Tolland , Tina is also the AC there. or Jen of Noblecraft K9 in Canterbury..I dont think either has puppies available however, if you know exactly what your looking for they may be able to refer you to someone that would suit your lifestyle.
I like ryanhaus gsd's in MA, and von hena c in NH..
However, if you don't have gsd experience, it may be rather daunting..
I think you need to sit down, write down what you want and don't want in a dog and contact the above for a referral or if any of them have something available to suit your 'want's and don't wants'.
Honestly, for me anyway, and I've had german shepherds my entire life, if I had a 2 and 4 year old I don't think I'd be getting them a german shepherd, something probably a little more sedate but that's certainly your choice
