The name Patrick originates from the Latin name Patricius, meaning 'nobleman'. It was notably adopted by Saint Patrick in the 5th century, a Romanized Briton who was captured and enslaved by Irish raiders. After escaping, he returned to Ireland as a missionary and is credited with Christianizing the island, making him Ireland's patron saint. The name was considered too sacred for everyday use in Ireland until the 17th century but has since become very common.
