French: from the Late Latin name Renatus ‘reborn’, used by early Christians as a baptismal name celebrating spiritual rebirth in Christ. It is found in the English-speaking world, especially North America, where it is usually written without the accent. It occurs occasionally as a girl's name, presumably a modified spelling of Renée or a short form of Irene and similar names.
Northern English: occupational name for a smith or worker in iron, from Middle English and Old French farrour, ferour, from medieval Latin ferrator, an agent derivative of ferrare ‘to shoe horses’, from ferrum ‘iron’, in medieval Latin ‘horseshoe’. Compare Ferrier and Farrow.
