Hmm, I get a light breed feel from his first couple of pictures, but in the last one, he almost reminds me of a Irish sport horse or something. It would help to know where you are located to single it down. I just don't think anything stocky like qh/paint. Unless he was a oddball stock horse that didn't come out right!
SHE really looks like a half or better Arab. Look at that tail carriage and the flat croup, and her face. So, I'm going to give him some Arab blood, but otherwise....?????, Pinto of some kind but unknow what mix.
