From the Roman family name Egnatius
, meaning unknown, of Etruscan origin. The spelling was later altered to resemble Latin ignis
"fire". This was the name of several saints
, including the third bishop of Antioch who was thrown to wild beasts by emperor Trajan, and by Saint Ignatius of Loyola (1491-1556), founder of the Jesuits, whose real birth name was in fact Íñigo.
