well here is the list of roman catholic cathedrals (!)
https://en.wikipedia.org/wiki/List_of_Catholic_dioceses_in_Great_Britain
quite a few I would have thought you cd see the roman one and the anglican - has anyone mentioned westminster cathedral ?
Pius IX re established the english dioceses 1850 and there was an outbreak of ecclesiastical panic - banning any legal force to any roman order or bishop -
(The Ecclestiastical Titles Act of 1851, which marked the last time the British government passed a legislation discriminating against a specific religion, resulted from an odd comedy of errors in which the parties concerned repeatedly acted in ways contrary to their own basic beliefs)
but three share the same name I was surprised to see as care was taken that the roman dioceses did NOT overlay the anglican
oh Liverpool of course - the red brick prot one is easily seem from Paddys Wigwam - the roman one
