Scottish and northern Irish: Anglicized form of Gaelic Mac Ruaidhrí ‘son of Ruaidhrí’ (see Rorie ), a personal name derived from ruadh ‘red’ + rí ‘king’. There is possible influence from the Old Norse personal names Hróthrekr (see Roderick ) and Hróthgeirr (see Rogers 2), forms of which were used as Anglicized equivalents.
