Raine f
English: of modern origin and uncertain derivation. It is possibly a respelling of the French vocabulary word reine queen (cf. REGINA (SEE Regina) and RAINA (SEE Raina)), or a transferred use of the surname Raine or Rayne. The surname is derived from various medieval given names beginning with the Germanic element ra(g)in advice, decision. In modern times, this given name is borne by the Countess Spencer, daughter of the romantic novelist Barbara Cartland and step-mother of the Princess of Wales.
