Riley—an upbeat, friendly surname name—is red hot for girls and still going strong for boys. If you haven't been spending much time around babies recently, you may be surprised to learn that Riley is the most popular girls' name starting with R and also the Number 1 Irish name for girls in the US.

Olivia, a lovely Shakespearean name with an admirable balance of strength and femininity, is the Number 1 name for baby girls in the US and one of the top girls' names around the world.

Grace, a simple and pure virtue name which originally referred to divine grace, is a fashionable classic. In the early 2000s, it seemed headed for the Top 10 but pulled back from the upward trajectory, which you may consider a very good thing.

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.

Audrey is one of the girls' names that have been rising due to their connection to Old Hollywood glamour — in this case the eternally chic and radiant Audrey Hepburn. Audrey has another very different appeal as one of the elite group of girl names that mean strong, brave, or powerful.

Chloe is a pretty springtime name symbolizing new growth. Though slightly off its peak in the Top 10 in 2010, Chloe still ranks in the Top 20 and is solidly a modern classic.

Emma has now been among the top girl names in the United States for several years, claiming the Number 1 crown in 2008 and again from 2015 to 2018 before dropping back to second place.

Elizabeth is one of the most popular girls' names of all time, the female equivalent of James or William. Yet Elizabeth has so much going for it—rich history, broad appeal, and timeless style—that no matter how many little girls are named Lizzie, Eliza, and Beth, you can still make Elizabeth your own.

Maya, which has an almost mystical image, has been steadily climbing in popularity in the US and the English-speaking world, along with a range of other countries, including France, Germany, Israel, and Brazil. It's ranked in the US Top 100 since the turn of this century, but has never risen to the top of the list, which you may consider a good thing.

Margaret is derived from the French Marguerite, which in turn came from Margarita, the Latin form of the Greek Margarites. Margarites was based on the Old Persian word margārīta, meaning "pearl."

Sabrina, the bewitchingly radiant name of a legendary Celtic goddess, is best known as the heroine of the eponymous film, originally played by Audrey Hepburn, and later as a teenage TV witch; it would make a distinctive alternative to the ultrapopular Samantha. Similar names you might also want to consider include Sabina and Serena.

Molly is one of the original nickname names, ALWAYS ranking among the US Top 500 girl names since statistics began, in 1880. Molly peaked in 1991 only to rise just as high again in 2011, and though softening retains a good measure of popularity and charm.

Sophia, which was the Number 1 girls' name in the US from 2011 to 2013, is among the top girl names in the Western World, with a sensuous sound and high-minded meaning. A real winner, Sophia reached the top of the charts without losing any—okay, much—of its sophisticated beauty.

Mia is an appealingly unfussy multicultural name that has enjoyed a meteoric rise up the charts and is now firmly among the ten top girl names. Mia has surpassed its mother name Maria as the Number 1 girls' name starting with M.

Zoe is one of those surprising names that has been on the Top 1000 nearly every year since 1880, but it's only since the turn of this century that it's ranked in the Top 100.

Emily may have dropped somewhat in the current standings, but it was the most popular girls' name for over a decade because it appeals on many levels: Emily is feminine, classic, simple, pretty, and strong. Emily is Number 1 among Gen Z names. It also has those nice literary namesakes, like Emily Dickinson and Emily Brontë.

Hannah is one of the nation's top biblical girls' names — it surpassed Sarah in 1998, and ranks in the Top 100 along with Elizabeth, Abigail, Chloe, and Naomi. Hannah is a name with many sources of appeal: Old Testament roots, soft and gentle sound, and a homey yet aristocratic image.

Madeline, a lovely name with a soft and delicate image, is an old-fashioned favorite that returned to favor in the 1990s, combining a classic pedigree with a cute nickname option: Maddie.

Julia was an ancient Roman imperial name given to females in the house of a Julius, as in Caesar. Its origin is shrouded in history, but possible roots include Latin iuvenis, meaning "youthful"; Greek ioulos, meaning "downy-bearded"; or Jovis, a form of Jupiter, which means "sky father".

Abigail has been in for so long -- the name has ranked in the US Top 100 since the late 1980s -- it's amazing that it isn't more out by now. But Abigail's biblical and historic roots make it a fashionable classic rather than a passing fad.
