Of relatively recent origin and uncertain etymology. It is first recorded in the 19th century. It may be a shortened form of Belinda, an adoption of Spanish linda ‘pretty’, or a Latinate derivative of any of various other Germanic female names ending in -lind meaning ‘weak, tender, soft’. It was popular in the 20th century, especially in the 1950s.
English: from the Anglo-Norman French personal name Auvery, a Norman form of Alfred. It could also be from a variant of the Anglo-Norman French personal name Aubri (see Aubrey). At least in the case of the original Puritan settlers in New England, there has been some confusion with Averill.
