Abraham is among the most classic baby names that's still widely-used today, popular for its references to both the Bible and American history. The Biblical Abraham was the first of the Old Testament patriarchs and is considered the founding father of the Jewish people. He was originally named Abram, until, according to Genesis, he was told, "No longer shall your name be Abram, but your name shall be Abraham, for I have made you the father of a multitude of nations."

This Elizabeth nickname has a decidedly retro feel--think Betsy Ross and the Betsy Wetsy doll-- once seen as a perkier, younger-sounding alternative to Betty. But with Betty on the brink of a comeback, pigtailed Betsy could return as well.

Like Friends, Ross is off the air and into syndication as a baby name, having plummeted from its zenith in the late 80s to fall off the US Top 1000 in 2013. Today, Ross is more likely to be a dad name than a newborn name.

Sam has long been used on its own for boys, as accepted standing by itself as it is as a short form of Samuel. Straightforward and down-to-earth, Sam is the name of the son of the co-stars of The Americans, Keri Russell and Matthew Rhys. Sam is one of the most popular names that start with S in the Western world, ranking higher in several European countries than it does in the US, where it's trended downward since the 19th century, though it's always been in the Top 1000.

Ellis, a surname used sparingly as a first in the Wallace/Morris period, sounds new now for girls, as a gender-neutral alternative to Ella or Alice. It debuted in the US Top 1000 for girls in 2015.-- Ellis has always been in the Top 1000 for boys -- and seems to be headed straight up. One of the most popular gender-neutral names, currently there are two baby boys named Ellis for every girl.

A sassy, spunky, punchy kind of name, Dixie can also be considered a place name, one that has become problematic because of its association with the antebellum South. The Dixie Chicks recently dropped Dixie from their band name because of its association with slavery and white privilege.

If Destiny is your daughter's destiny, she probably won't be the only one in her school: until 2009, Destiny was in the Top 50, with three of its alternate spellings in hot pursuit. It has since dipped a bit in popularity but is still widely used. Destiny Hope was the birth name of Miley Cyrus and Destiny Jones is the daughter or rapper Nas.

A popular choice back in the 50s and 70s, Rocky fell into decline after Sylvester Stallone's battered but not beaten boxer character became the overwhelming association many had with the name. Now, nearly five decades on from when the first Rocky movie was released, this tough yet playful name is back in style, ready to forge an identity of its own. Given to around 420 boys in the US in a recent year, it was one of the fastest rising names in the charts.

With its relation to Mount Olympus, home of the Greek gods, and to the Olympic games, this name has an athletic, goddess-like aura, making it the perfect Olivia substitute.

A Native American tribe name which is found in the names of two US states, Dakota was one of the first trendy nineties place names, but is now flagging a little in popularity. The cultural question around using a Native American tribe name as a baby name may be partly to blame.

This once unique and multi-layered word name was used by R&B singer Nivea for her daughter back in 2005, and later, by country musician Jason Aldean. No longer an exclusively celebrity choice Navy is now in the US Top 500 for girls and is on the rise in the UK too. As a boys name, however, it remains an unexpected possibility.

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.

A name with a bit of glamor but also cowgirl vibes, Dallas entered the US Top 1000 for girls in 1992. It fell out of style during noughties, but reappeared in 2012 when other gender neutral names like River, Sawyer, Rowan, and Blake were also climbing fast.

Extreme makeover: Brooklyn has gone from jokey Borough Boy name in the 1990s to a leading girls' name starting with B. The status of New York's Brooklyn as hipster heaven is ironic as few bona fide Brooklyn hipsters would choose this name.

Inextricably tied to the former president, Reagan is a handsome surname name with a cool, current sound. Gender-neutral nickname Ray/Rae is also very on-trend right now.

Honor is a somewhat more straight-laced virtue name than Hope or Grace, placing a high standard on any girl carrying it, but it's a goal worth setting. By choosing Honor for her daughter, Jessica Alba brought it very much into the modern world.

Before there was Aspen, Denver was the Colorado city name of choice, and it reentered the US Top 1000 in 2015 after a 14 year absence as a stylish two-syllable boys’ name with its trendy -er ending. Its decade of greatest use was the 1920s, when it reached as high as Number 422.

Relaxed western place-name that still has some masculine punch, but be warned: this whole posse of similarly trendy names, like Sierra and Dakota, will soon ride toward the sunset.

West is the most fashionable of what you might call the direction names, with North and East (or Easton and Easter) coming up behind, and South not yet on the map.

Less common than other virtue names, Liberty is nonetheless a name with a long American heritage.
