Calvin is a slightly quirky but cozy name that has a fashion edge thanks to Calvin Klein. It has been steadily on the popularity list since records were kept, never lower than Number 250, peaking in the 1920s, the era of the Calvin (originally John Calvin ) Coolidge presidency. 
 The name came into use as a first name in honor of John Calvin--born Jehan Cauvin-- the seventeenth century French Protestant reformer whose strict doctrines became the basis of Calvinism, and the name was taken up as a tribute to him.
 Other associations include the above-mentioned Calvin Klein (and his famous 'Calvins' ads), humorous writer Calvin Trillin, the comic strip "Calvin & Hobbes" --and it's also the birth name of Snoop Dog. Calvin O'Keefe is one of the main characters in Madeleine L'Engle's A Wrinkle in Time.

Cassius, a Shakespearean name rooted in antiquity, is trending in a major way. It's one of a raft of Cas-starting names for both boys and girls, including Caspian, Cassian, and Cassia, that are enjoying a new moiment in the sun.
 
There were two notable Ancient Roman figures named Cassius. Cassius Dio wrote an 80-volume history of Rome. Gaius Cassius Longinus, a senator who led the assassination plot against Julius Caesar, is the main figure in Shakespeare's The Tragedy of Julius Caesar. 

 In more modern times, Cassius Clay was an abolitionist and also the birth name of boxer Muhammad Ali. It was chosen for their sons by singer Bobby Brown and Getty heir/actor Balthazar Getty. Vanessa Marcil and Brian Austin Green used the nouveau Kassius spelling for theirs. With these namesakes, it's no surprise this name has become popular in recent years. 

 Americans tend to pronounce the name CASH-us while Europeans, including the British, say CASS-ee-us. Cass and Cash are both accessible nicknames.

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. Iconoclastic namer Jason Lee switched genders and called his daughter Casper. Also related to the revived Jasper, Caspar seems headed towards the path to a similar resurgence.

 Caspar is the name of one of the Three Magi who brought gifts to the infant Jesus&mdash;-Caspar of Tarsus was the one who brought the gift of gold.

 In the Casper spelling, the name was quite popular in the U.S. near the end of the nineteenth century, peaking in 1889 at Number 332, but it dropped off the list completely in 1933. It still retains its popularity in Scandinavia and Belgium.

 Actor Casper van Dien was the tenth generation in his family to bear the name of his Dutch ancestors, continuing the tradition with his son Casper Robert Mitchum.
