i was busy updating ban bori article added many new and reliable references it should be obvious now that he having been an illegitimate son of a hungarian king was also the first viceroy of the then newly created banate of bosnia where he ruled as autonomous sovereign since he's the first first then he is considered the founder of the house as well the house is sometimes referred to as bori evi but this is probably just to honor him because i've never heard of a one man royal house so i say we stick with bori as the founder of the house of berislavi meaning house in historic legal sense of course or as royalty if you wish
