U.S. Presidents and Vice Presidents

Jonathan was derived from the Hebrew name Yehonatan, eventually contracted to the modern Yonatan, meaning "gift of Jehovah." It comes from the elements yeho, in reference to God, and natan, meaning "to give." In the Old Testament, Jonathan was the valiant eldest son of King Saul, and it was his friendship with brother-in-law David that gave rise to the expression "Jonathan and David" to describe devoted, steadfast friends.

Joseph is one of the most classic names in American nomenclature, popular with parents from many ethnic backgrounds and having dual-religious appeal.

Josephine, with its large measure of class and character and a gently offbeat quality, has been on a gentle uphill climb in the US for over 30 years, now ranking in the Top 100. With an intriguing number of vivacious nicknames, from Jo to Josie to Fifi to Posy, Josephine is a Nameberry favorite.

Josie is jaunty and friendly: among the most winning of all nickname names. She's been on the social security list since records began being kept.

In many minds this one belongs to Barbie, but with such positive meanings and international connections, can Ken make the transition to usability again?

Kendall, as used for a girl, was initially propelled by a soap opera character (Sarah Michelle Gellar as Kendall Hart in All My Children) and reality star and Kardashian sister Kendall Jenner.

Kendra was once seen as a feminization of Kenneth -- but it's now firmly established as a standalone. American parents can't seem to make up their mind about it though: it was one of 2013's fastest-rising names, entering the Top 200 for the first time since 2000, but then it tumbled again.

Kenna is the Scottish version of Kendra, both of which are feminine versions of Kenneth. Used in the TV show Reign for one of the supporting characters.

This attractive surname name still projects that Kennedy family charisma. While it didn't come into widespread use until long after the deaths of martyred heroes President John F. or Senator Robert Kennedy, Kennedy is now one of the most popular unisex names for girls as well as the top girls' name starting with K. This is one name that manages to sound trendy and classic at the same time.

Kenny might be all South Park to some, but it has been in steady use in the US since the 1930s.

King is a name that sends a mixed message. While some might think of it as more fitting for a canine, others see it as a strong name with offbeat style and a full court of rich associations, from Dr. Martin Luther King Jr. to Elvis.

King Vidor was an important early Hollywood director; King Camp Gillette invented the safety razor.

Kingsley is a sophisticated Harry Potter name that entered the US Top 1000 in 2013.

A Scottish surname name, more popular as the Presidential McKinley, meaning "son of the fair hero".

A name that has a bit of a shouldn't-I-be-a-middle-name sound, though still in use as a first for both genders. Lee might be a good choice if you want something that sounds at once traditional yet modern, unisex but not newly-minted.

Levi, lighter and more energetic than most biblical names, with its up vowel ending, combines Old Testament gravitas with the casual flair associated with Levi Strauss jeans.

Lincoln cracked the Top 50 for boys' names for the first time in 2016, more than 150 years after the death of its most famous bearer. This is especially remarkable because, as crazy as it seems now, Lincoln was deeply out of fashion as recently as the late 90s, consistently hovering near the bottom of the Top 1000.

Linda will live forever in baby name history for toppling Mary from its four hundred year reign as Number 1. Queen of Names in 1947, Linda has fallen even further in favor than Mary today.

Groovy Mod Squad name that still sounds retro cool.

An English surname-turned-first-name whose most famous bearer is former US president Lyndon B. Johnson. His appointment in 1963 caused a huge spike in use for his unusual name the following year, pushing it to its historical peak of #347 in 1964. However, the year after his exit from the Oval Office, it dropped back below the Top 1000.

Lynn arrived in the 1940s, spinning off from the wildly popular Linda, to become a top midcentury middle name. Now, Lynn's in limbo.
