I'm also in NJ, Bergen County. My breeeder is in Northern New Hampshire. She does travel to Boston to meet families though. I'm actually meeting her in CT next month to pick up my new little girl. She has 2 litters that will be ready to go home around May 24. I'm positive she has a larger boy who needs a home, 8lbs expected maturity. I don't know if she has a girl. Here's her website if you're interested:
Clover Hill Yorkies. Her name is Susan. She's wonderful! My experience with her has been truly exceptional.
