Went to his FB page, clicked on the "about" and then googled his sire's name to get the correct spelling as that isn't even spelled right, and then put it in allbreed, then clicked on progeny.
His full AQHA number was on the about section too. You were just one number short.
It's irritating that they can't/wont put his name on his page correctly and then has his sire's name misspelled. *sigh*
