Have you done a search on Petfinder? Sometimes there are yorkies in shelters on there...and they SO need homes. I have seen a few lately in NY.
There are groups in the East and Northeast. One is in Massachusetts...which is not all that far from you. They are:
www.yorkiesinc.com They are a very reputable group. If you adopt from them, there will be no surprises. That is also important when you speak with rescues....ask them what vetting is included in the adoption fee...AND what medical issues the pup may or may not have. A good group will have taken care of all medical needs, including spay/neuter and shots...and dentals if needed.
Some of the national rescues also have foster homes in your area.....look on Petfinder and if you have any questions, please feel free to PM me.
Good luck in your search!
