Deletion of Mariano Hugo of Windisch-Graetz

Comment: but would accept '''Merge''' - Gut feeling. I have been watching and "contributing" to this article for a while now, although my contributions have usually been of the deletionist tendency in this instance. I have no particular qualms regarding royalty/pretenders/ancient lineages & titles etc but this has been one of several articles where a certain person, often using IP addresses, has attempted what appears to be COI promotion. There has been tendentiousness and blocks galore. Yes, the subject appears as a part of genealogical studies and, yes, he does have some honorific/ceremonial function at the Vatican which puts him in a position of a "passing mention" in news reports etc. And the news reports of the death of his son strike a emotional chord. But during the time of my involvement with the article I cannot recall any real substance. As things stand, there still remains nothing to indicate that he has any influence (can't think of the most appropriate word for this) beyond his ceremonial and hereditary rites of passage. Many of the hereditary peers of the British House of Lords managed more than he has done in terms of notability. Both of which apply to the family line rather than the individual. Are we really to become a genealogical website? Indeed, notability (on WP) is not inherited. If we are to become a genealogical site then let it at least be contained to one article unless there is ''real'' substance to a broader claim under
