Anglicized form of the Gaelic name found in Ireland as Ruaidhrí and in Scotland as Ruairidh (see respective appendices). In Scotland this is further Anglicized to Roderick. In recent times, Rory has come into popular general use.
English: habitational name from Lenton in Nottinghamshire, which is named from the river on which it stands, the Leen (see Leen) + Old English tūn ‘settlement’, ‘enclosure’. There is also a Lenton in Lincolnshire; however, up to the 18th century it was known as Lavington and probably therefore did not contribute to the surname.
