Welcome to QQ, Flo! Wales sounds like a charming part of the world; I've never had the privilege of visiting there.
Several years ago my wife and I attended the annual meeting of the 19th Century Studies Association. One of the highlights was a paper on "the Welsh Revival." Other than my own humble offering, the Welsh paper is the only one I remember.
It would be interesting to hear more about your spiritual pilgrimage, and about the Society of Friends in Wales.
