Cal is a nickname style name that feels as friendly and calm as it does cool and breezy. While its longer forms have proved more popular over the years, Cal as a stand alone has dropped on and off of the US Top 1000 since the 1880s.

Artistic associations with the sculptor who invented the mobile make this one of the more creative surname choices.

A beaming, friendly Irish last-name-first-name waiting to be discovered.

In Shakespeare's The Tempest, Caliban is the name of the deformed son of a witch: not the greatest literary reference for a child. But Caliban does have an appealing international-yet-accessible feel and a rhythmic sound. As long as nobody knows its origin, it might make a great name for a boy or even a girl.

After half a century, this otherwise feasible name has at last started to lose its link to the friendly ghost; it certainly didn't scare model Claudia Schiffer, who chose it for her son, as did Atomic Kitten Jenny Frost.
