Deletion of Principality of Dukagjini (2nd nomination)

Comment: per  and . I'm having difficulty verifying the sources. In Imber (2019), there is no mention at all of Dukagjini. Malaj (2016) appears to be privately-published |original research. Fine (1994), literally mentions the family once, in a single sentence. Trnavci (2010), mentions the Dukagjini family half a dozen times over two pages, but never once as a principality or any other legal entity. There's evidence this family existed, but not any actual state nor their titles of nobility. Nobility are not automatically notable, and we need to verify that a state existed
