From the Latin name Patricius, which meant "nobleman". This name was adopted in the 5th-century by Saint Patrick, whose birth name was Sucat. He was a Romanized Briton who was captured and enslaved in his youth by Irish raiders. After six years of servitude he escaped home, but he eventually became a bishop and went back to Ireland as a missionary. He is traditionally credited with Christianizing the island, and is regarded as Ireland's patron saint.
