She looks like a yorkie to me!! Of course, I'm no expert. I'm sure the more experienced breeders here will give you a better idea.
By the way, I think it is incredibly rude for anyone to tell you what your dog is or isn't!
Your aunt and those other people need to mind their own business! I've had people tell me their dog is this or that or their cat is this or that when it is obviously a cross/mix, but I would never tell them otherwise and I certainly wouldn't tell someone their purebread yorkie is really a silky. The nerve of some people!
