The father went to Jerusalem to find his son, fell ill, and was nursed by him without knowing it.
The tradition of Foggia brings them from Antioch, father and son. Pellegrino, the only child, left the family's comfort while still young for Jerusalem, where he served without pay in a hospital. William, left alone, sought news of him for a long time and at last set out himself to find him, old as he was. Reaching Jerusalem he fell ill and was taken into the very hospital where his son worked. The father did not know him; the son knew him and kept silent, fearing to be turned from his task. At last he made himself known, and the old man recovered. They set out together, gave away everything they owned to the poor, landed at Brindisi and walked from shrine to shrine — Saint Nicholas of Bari, Saint Michael of the Gargano, the Incoronata — as far as Foggia, where they became hermits. The old man died first; the son was not long in following him — the Foggia tradition, for its part, has them die on the same day, embracing before the Marian image of the city. Foggia took them for co-patrons, beside its Madonna of the Seven Veils; their bones lie in an urn in the cathedral, authenticated in 1630, and a parish bears both their names.
