Forgot about that. Will have a look later.
Just tested my theory on the Who link being dubious. Mike Wakelin was born in Essex in 1941 as Michael A Wakelin. He doesn't show up in the GRO up to 2021, isn't in the Probates after that, and according to 192.com, was alive as recently as 2020. Looking like he's still around, so Hoather probably isn't the only surviving member, hence the odd wording in the link.
