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.

This spirited Gaelic classic, which became popular in Ireland via the illustrious twelfth century king Rory O'Connor, makes a highly energetic choice, now used for either sex. Rory's gender split is still trending boyward; it's one of the coolest <a href="https://nameberry.com/search/boys-names/r">boys' names starting with R</a>. 
 In England and Wales, however, the name is virtually never given to girls. It's seen as thoroughly male (and non-female) as Roger or Richard.
 Rory first came to attention in the US in the person of mid-century pin-up boy Rory Calhoun (born Francis Timothy). The name entered the popularity list in 1947, peaking at Number 280 in 1959. 
 Young Irish U.S. Open champ Rory Mcllroy makes a worthy namesake. Bill and Melinda Gates chose Rory as the name of their only son.
 Rory is a popular choice all throughout the UK. Skip baffling Gaelic spellings like Ruari and Ruaidhri and stick with the more straightforward Rory.
