As written in the article Vasojevici are mentioned for the first time in   that is undisputed Yet another hundreds of years passed before Vasojevici were properly described in any written sources Vickers claims that Albanian Vasojevici were being assimilated in the middle of XII century so her claim is clearly based on a very old word of mouth presumably Albanian one So here you go she also believes in legends   But seriously speaking   you have provided one unreferenced sentence the author does not provide her source   from a book on Kosovo not on Vasojevici or at least on Montenegro  Vasojevici are mentioned in that book once only  that has been published in  book on Osetian history written during Russian intervention might be a little bit biased dont you think   written by a scholar that is so fond of Albanian history that even speaks Albanian  On the other hand you have long list of books and sources on Vasojevici see bibliography and references below some of the more than  years old eg Vasojevicki Zakon u Dvanaest Tocaka many written by Vasojevici themselves eg Cemovic Vesovic and nether even once  is this Albanian ancestry mentioned Not only dont they mention Albanian ancestry but they even give probable names of Vasojevici ancestors back to the begining of XII c and that is before alleged assimilation Vukan Kostadin Vasoje Stevan Kostadin Vaso Novak Vujica Have you noticed any Albanian names  We will definitely need some more grounded sources to include information of Vasojevici Albanian ancestry into the article not to mention crating a separate onesentence chapter about this  regards
