Deletion of Hohenzollern impostors

Comment: Regarding secondary sources,  states that notability requires 'significant coverage in multiple published secondary sources that are reliable, intellectually independent of each other, and independent of the subject'. My question is whether two is multiple. In order to substantiate a keep, there should perhaps be one more source, preferably in English or German

Comment: fails .  the question at issue here is not whether the Fosse family of Bergen, Norway is or is not descended from an illegitimate child of a Hohenzollern, it is whether this alleged illegitimate descent claim  meets .  If more sources exist, I can't find them

Comment: In general, I dislike this type of |repositories because they are duplicative, increasing the risk of erroneous information being reproduced and not being corrected (not least considering the already dubious nature of such articles plus sources), whereas I prefer to gather all such information in one place. Thus, there shouldn't be a Hohenzollern impostors article but a :Category:Hohenzollern impostors|Hohenzollern impostors category to include ''independently notable'' articles like Harry Domela.—This brings about a new question: Are the Fosses notable enough for their own BLP article which could be included in :Category:Hohenzollern impostors? The way I perceive it, the creator of this article has established a Fosse BLP under false name in order to avoid BLP criteria. If the Fosses are eligible for their own article, the contents should (promtly) be moved to Fosse family (Bergen, Norway), Fosse–Hohenzollern case or similar. If the Fosses are not eligible for their own article, they are perhaps not eligible for an article-length section
