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.
Respelling of a Scandinavian and North German patronymic derived from the Old Norse personal name Eiríkr, which is composed of ei ‘ever’, ‘always’ (or a reduced form of ein ‘one’, ‘only’) + rík ‘power’. The main forms are Erichsen, Eriksen, Ericsson, and Eriksson.
