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 Middle English personal name Wymer, Old English Wīgmǣr (composed of the elements wīg ‘war’ + mǣr ‘famous’), reinforced by the cognate Continental Germanic form Wigmar, introduced into England from France by the Normans. This also became confused with an Old Breton personal name, Wiumarch, composed of the elements uuiu ‘worthy’ + march ‘horse’.
