Thanks everyone. I was definitely concerned at first when it popped up, but my fears are resting a bit. I'm trying to do more research into her lines. I'm not as familiar with as many paint lines as I am QH, but I'm hoping to learn more now that I seem to have come into owning a million paints. O_o
I'm not sure what that sire had that they liked so much they felt the need to line breed him, but maybe in my research I'll find more out.
I'll update with more research!
