I have a puppy from Olympia Kennels (located in southern NH) that I've been pretty happy with so far. He's a little over three months, so I can't tell you anything about his long term health, but he is a happy pup who seems to have a really good temperament. He's outgoing and friendly with other dogs and confident around other people and in unfamiliar situations. Except for the occasional mistake, he picked up housebreaking very quickly.
He does have moderate prey drive, is pretty exuberant and, if he isn't sleeping, seems to need a lot of attention/play time. I am also having to spend a lot of time on teaching him not to nip when he plays (which might be an issue for you with a small child). It's been 13 years since my last puppy, so I'm not sure how much of this is normal GSD puppy behavior and how much is specific to him.
Olympia breed mostly WGSL, but use a lot of Kirschental lines which were traditionally herding dogs. There are also a number of WGWL breeders that I know are well thought of on the forum (some of whom I have spoken with or have a little experience with).
Abby Kennels in northern Mass. (Chelmsford I think) seems to produce solid dogs, but the one's I've met also have pretty strong drives and might not be the best match for you. If you are interested I would contact the breeder, who is also a very experienced trainer and would be able to tell you if his dogs would be a good fit.
People also seem to really like von Ryan Haus as a breeder. I've also spoken with her and was pretty impressed. I think she'd work hard to match you up with a dog that would be a good fit. Von Hena C also has a pretty good reputation on this forum. I also liked the breeder at Kavallarie Shepherds who I spoke with at some length (although she is in Northern Vermont, so it might be too far for you).
