Historical and Cultural Context The root name Patrick has deep historical significance due to Saint Patrick, the 5th-century patron saint of Ireland. He was a Romanized Briton who was enslaved in Ireland, later escaped, and returned as a missionary to Christianize the island. Saint Patrick is celebrated on March 17. In Ireland, the name Patrick is common but was not used until the 17th century because it was considered too sacred. Patricia, its feminine counterpart, is well-known in bearing and transmitted globally.
