Calling bullshit on this one. It's been a week, and although the Viscount Falmouth and his family are very private, there would be a death notice in a broadsheet now for any Earl or Viscount.
Problem on Wikipedia was 2 experienced users continued to edit his page and created a new page for the presumed 10th Viscount, after an anonymous IP edited his page to say he had died. They did this without confirmation of his death, which is somewhat embarrassing. Given that these users frequently edited aristocrat type pages, it seemed safe to assume they were in the know. Both users now admit they just believed the initial edit from the anonymous IP.
I will scrub the initial post later once this has been read.
