Felix

From the Latin adjective felix, meaning happy or fortunate, Felix was a common name in ancient Rome and appears in the New Testament as the name of the Roman governor Antonius Felix, before whom the apostle Paul appeared. It was adopted by early Christians partly because of its auspicious meaning and was borne by numerous saints and four popes, which helped spread its use across medieval Europe. The name remains widely used across European languages, with the French and Spanish form Félix, and gave rise to the feminine form Felicia as well as the related name Felicity.
