(f) This derives from a Roman clan name,
probably based on Latin valere, ‘to be strong.’ First
use of the name in Britain was in the form Valeria, but the French
Valerie soon became more popular. Valerie became especially fashionable
around 1950, and reached 46th position in Scotland in 1958. It
is now little used. The masculine forms of the name, Valerius
and Valerio, do not seem to have been imported into Britain.
