Could it have been St Nilus?
Turns out it seems to be fake, at least according to Jim de Piante. If you're in the SSPX group, you can view this post: https://www.facebook.com/groups/1239467472807150/permalink/4466060420147823/. Although his explanations are not particularly exhaustive. Also, I found the facebook post I was referring to, and there was no mention of "not being able to tell what country they come from." Feel free to largely disregard what I said about this "prophecy."
