Indeed. If one's source cannot give a reliable account of the witnesses, what else are we to find reliable about its account?
In consequence of her experiences at Fatima, Lúcia Santos consecrated her life to the service of Jesus Christ as a Discalced Carmelite nun. She lived a very long time, IIRC.
Also IIRC, either one or both of her cousins Jacinta and Francisco Marto died before attaining adulthood.
Whatever. The three witnesses were not three sisters.
That’s a fault of my faulty memory, not of the sources.
Some details I don’t carry well in my head, particularly long term.
The list of points I typed above were all out of the top of my head. They are essentially accurate. That detail was wrong.
You are welcome to trash my assertions accordingly, if you wish.
I wouldn’t consider it wise, however.
