[Teresiana]

I'm in the process of searching for my next pup & have 3 breeders on my "short list". I'm looking for a PET. I was wondering if someone could shed some light on the various Yorkie "lines". I tried Google, but I get a very broad search result & I'm not sure exactly how to tie everything together.

Pardon my ignorance, as I am an owner of 2 rescue pups. I have decided to work with a breeder this time & I just want to make sure that I'm educated as I can be about the pup I will be purchasing. I also want to be able to ask my breeder the right questions.

Are some lines better than others?
Do certain lines have a reputation for certain characteristics?
What does "based on such-and-such a line" exactly mean?
What does "descended from Clarkwyn breeding" mean?

Some lines that have popped up in my breeder search include: Wildweir, Clarkwyn & Edgewood.
