I think that if a person can trace their founding animal back directly to the breeder that the line is named for then they sould keep the line name..

But like me I got my Pastel Jungles from EbN who got theirs from who knows who. I can't call them Graziani Line pastels because in my mind they aren't.. My Bee however is a direct from NERD so the Pastels it produces are NERD Line pastels.
