Thanks for all that info! There have been so many apparitions, most of them non-sanctioned, that I don’t know them all. I only learned of “Our Lady of Knock” when we moved up North. I guess there weren’t enough recently arrived Irish folks where I grew up, as there are up here in MA.
I don’t think anybody could keep track of all the apparitions, even the ones that have been officially approved by the Church. La Salette was declared authentic in the 1850s, Knock never has been officially, but JPII made a pilgrimage in 1979.
