Names fall in and out of favor over time. Old ones are revived and new ones are created, and suddenly every kindergarten seems to have a Demi or a Dax. 24/7 Wall St. compiled a list of American names popular for the first time.

Some of the names on our list have biblical origins, some have Greek and Latin roots, and still others were originally surnames. Some — such as Winter and Wren — are also words in everyday use, while others look like they might have been misspelled. Our list shows the influence of pop culture as some newly popular names are shared by celebrities, or by characters in movies and television shows.

We found some interesting quirks and coincidences. The American Revolution was fueled by a desire to have a president rather than a king, yet Royalty is an increasingly popular name. Another entry on our list, Nixon, was the surname of a president who left office in disgrace.

To identify the American names popular for the first time, 24/7 Wall St. reviewed the popularity of baby names in the United States each year between 1880 and 2017 using data obtained from the Social Security Administration. To be considered for this list, boy or girl names needed to have never reached the top 500 most popular names until 2017. These are the only 17 names that meet that criteria. All data was obtained from the Social Security Administration, which publishes data for names with five or more occurrences.

This is an ancient Greek name — Leonidas was the warrior king of Sparta who died fighting the Persian army at the Battle of Thermopylae.

12. Nixon
> 2017 occurrences: 603 boys

Nixon originated as a surname and its appearance on our list may surprise some, given the notoriety of the 37th president of the United States. For whatever reason, it has become particularly popular as a first name in Utah. Singer Beyoncé has a half brother named Nixon.

15. Royalty
> 2017 occurrences: 747 girls
> 2017 rank: 421th

The meaning of this girl’s name is obvious — and its appearance on our list may have something to do with the popularity of the British royal family. Royal itself has been somewhat popular as a boy’s name. Perhaps the recent marriage of Meghan Markle to Prince Harry will give both yet another boost.

16. Winter
> 2017 occurrences: 699 girls
> 2017 rank: 449th

Summer and Autumn have long been established as first names, so perhaps it’s no surprise to see Winter on our list. It’s hard to think of a famous Winter, although “Winter is coming” has become a catchphrase from the successful television series “Game of Thrones.”

17. Wren
> 2017 occurrences: 668 girls
