Twins names

Caroline is a perennial classic, one of the elite group of girls' names that's ALWAYS ranked among the Top 1000 and that's been in the Top 100 since 1994. Elegant yet strong, Caroline calls to mind the Kennedy Camelot years and Princess Caroline of Monaco.

In the USA, Hattie is one of those nicknames that is now more popular than its parent name, Harriet. In England, however, Harriet is still by far more popular than Hattie, while in Australia, Harriet is highly popular while no data exists on Hattie. In the US, we’d like to see Harriet get more usage but we’re happy to see Hattie again.

Jack may have fallen from its Number 1 place in England, but in the US it's as popular as it was at its height in the 1920s and 1930s. A durable, cheery, everyman form of John, Jack ranks as one of the most popular boy names starting with J.

Chic in the fifties, now kept in the public eye mainly by actress Zellweger. Variations include Rene, Renae, and Renny.
