I found the holy cards while looking through Mother's old cards in Brazil and also photographed a few other ones. I don't know if she was ever in the Saint Bathilde Priory in Vanvers, I suspect she liked and bought these in one of her trips to Paris or in Metz, where they lived for a year before I was born. I have posted about this dear saint before, here and here , and I close with this prayer posted 3 years ago:
whose favor with God was such as to bring about a mighty
storm, bring about for me, who has loved you since infancy (when the Benedictine
sisters in school would give me holy cards with your image), that I may
persevere in God's love, allowing Him, whose Infinite Wisdom is unfailing, to
guide all of my days. Amen.
