Fulk

Saint Fulk was a pilgrim to Rome who gave his life tending the plague-⁠stricken at Santopadre (Castrofuli) near Arpino in southern Italy. He is regarded as patron of that area and is commemorated on 22 May.

The sources disagree on his time: the list we follow places him around 600, while Wikipedia has him as an English pilgrim of the twelfth century who stopped at Santopadre on the way to Rome, helped the plague victims even at risk to himself, and died of the plague. His cult was approved in 1572.
