I would take her to the vet and have her checked out , not only to see if she is microchipped, but to see the age of the yorkie, perhaps how long she may have been on her own, if she has been "starved" , matted, and these type of things. This will indicate how long she has been away , or lost.
I feel so bad for this little Yorkie. I am glad that your family took her in. If all else fails and you can't keep her, maybe she can go to a yorkie rescue? Or someone on YT can give her a new , wonderful, loving home?
