Diego

Possibly a shortened form of Santiago. In medieval records Diego was Latinized as Didacus, and it has been suggested that it in fact derives from Greek διδαχή (didache) meaning "teaching". Saint Didacus (or Diego) was a 15th-century Franciscan brother based in Alcalá, Spain. Other famous bearers of this name include Mexican muralist Diego Rivera (1886-1957) and Argentine soccer player Diego Maradona (1960-).
