Bah. I wish allbreed had pictures of all the horses. I am not an AQHA member so I can't get into their database of horses either. Judging from Chics Texas Twister's get on facebook, a few of them had facial markings that looked like they could be caused by frame. However, there were no pictures of their dams either.
Did you breed the filly? Or did you buy her from a breeder? If you bought her from a breeder, you could email them and ask if they know the OLWS status of their stallion and mare. If you bred her from one of your mares, you could still email and ask the status of the stud.
