Mainly North American and Australian: as a boy's name this originated as a pet form of Randall, Randolf, or Andrew. As a girl's name it may have originated either as a transferred use of the boy's name or else as a pet form of Miranda (compare Randa). It is now fairly commonly used as an independent name, mainly by men, in spite of the unfortunate connotations of the colloquial adjective meaning ‘lustful’.
English and Scottish: occupational name for a tailor, from Old French tailleur (Late Latin taliator, from taliare ‘to cut’). The surname is extremely common in Britain and Ireland, and its numbers have been swelled by its adoption as an Americanized form of the numerous equivalent European names, most of which are also very common among Ashkenazic Jews, for example Schneider, Szabó, and Portnov.
