I found a comprehensive list of worldwide marian apparitions along with the status and findings. I cannot vouch for the accuracy but it will be a good start for reference.
Please join the Missionaries of Charities in praying the novena to their founder, our dear Blessed Mother Teresa of Calcutta, for her feast day, September 5th. The novena can be found here.
A special mahalo nui loa to Sr. E. for sharing the novena with me.
