Help Sought

I said a while ago that I was working on a piece about the reception of Humanæ Vitae by the Church in England and Wales, but I have fallen into a deep and interesting (and possibly significant) rabbit hole: how influential were some of the lay organisations in the Church in England and Wales at the time of the Council and subsequently.

I'm interested in how they became influential: whose agenda was suited by support from lay organisations?  Who provided them with ecclesiastical support?

And how far were they used by "progressive" Bishops and clergy to leapfrog their more conservative confrères?

I'm thinking of organisations like the Laity Commission and the Newman Society, in particular in the early phase, but there might be more. Later on you come across lots more.  I obviously don't mean the KSC, SVP, UCM or CWL: PBI, to add another TLA to the list.

The Hierarchy in England and Wales has always actively sought "representative" laity, from the Catholic Union in the latter part of the nineteenth century to Catholic Voices in the twenty-first, representative, that is, of what the Hierarchy thought lay Catholics should be like; but what I'm chasing down here are the relationships between key members of the Hierarchy and key members of what became key lay organisations.

Any pointers gratefully received.
