Thanks for this @YoungWillz! That is indeed a death notice for Cresswell. As there was only one Curtis Cresswell born in 1946–1948, plus the area concerned is also a match.
As for the others, I will add a note to the listing with that Who link. The wording bothers me slightly. It says "the surviving". If they had said "the last surviving" then I would have been more happy to mark all the others as deceased but I want to err on the side of caution to make room for any potential oversights.
