I have been able to get a copy of an old copy of the oop book: "St. Anne: Grandmother of Our Saviour" by Frances Parkinson Keyes. It is a nice, big book that has three parts to it - 1. The Life of St Anne - 2. Cult of St Anne - 3. Songs, Poems and Canticles of St Anne. I'm quoting parts from the 'Cult of St Anne' section, as the shrine of St Anne deBeaupre is discussed in depth.
It owes its foundation to a vow made by a small group of Breton sailors, who landed there in1658 after having been saved from shipwreck, and who attributed their rescue to the intervention of St Anne, to whom they promised a votive offering."
Votive Offering from the St Anne, Rear wall, Memorial Chapel, Ste. Anne de Beaupre.
