I wonder what the collective word is for holy well experts?

Field visit to St Declan's Well, Ardmore today. The women in costume are not New Age Pagans but are delegates to the Holy Well conference from a St Bridget's holy well in Sweden (and one is a blacksmith too). I must say this was a truly interesting group of people and the conference was a great success.
Extra is Herself in action this morning in a rather bunker-like room in the museum in Waterford.
