Lucas is a Top 10 boys' name with a slightly-less-popular almost-identical twin brother, Luke. Like Elijah and Elias, Lucas and Luke come from the same root and have the same meaning and so feel even more popular than they are.

Eliza is a name with a wonderful combination of streamlined zest and Eliza Doolittle charm and spunk. It's a classic that's popular right now -- but not too popular.

Alexander has been in a Top 25 boys' name in the US for 30 years now. But namers are still attracted to its imposing historic pedigree.

The quirky, offbeat and energetic botanical name Ivy is enjoying a deserved revival, propelled even higher by its choice by high-profile parents Beyonce and Jay-Z for daughter Blue Ivy. Ivy is also traditionally used at Christmas, make this one of the perfect names for December babies.

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.

Catherine is one of the oldest and most consistently well-used girls’ names, with endless variations and nicknames. The Catherine form feels more gently old-fashioned and feminine than the more popular K versions. Most stylish nickname for Catherine right now: Kate...or Cate, a la Blanchett.

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.

Evan has a mellow nice-guy image that has kept it popular, while it has been widely used in Wales since the nineteenth century. And interestingly—and surprisingly—enough, Evan charts highly for boys in France.

Iconoclasts though we may be, we like Fred, we like Frank, and we like George, which was among the Top 10 from 1830 to 1950, when the number of little Georges started to decline. Solid, strong, royal and saintly, yet friendly and unpretentious, we think that George is in prime position for a comeback, especially since it was chosen by Britain's royal couple.

Anna has become the dominant form of the Ann family, offering a touch of the international to English speakers and a bit more style than the oversimplified Ann or Anne.

Philip, the name of one of the 12 apostles, is still favored by parents in search of a solid boys' classic that is less neutral than Robert or John and more distinctive than Daniel or Matthew and has many historic, royal ties.

The name Veronica projects a triple-threat image: at once saintly, sensuous, and strong. The name derives from Berenice, the Latin form of the Greek name Berenike "she who brings victory", with the spelling influenced by the Latin phrase vera icon "true image". Veronica was the name of the compassionate woman who wiped Jesus's face when he was on his way to Calvary and whose cloth was miraculously imprinted with his image: she is now the patron saint of photographers.

Alana, in all its various spellings, was at one time reserved for daughters of dads named Alan, but is now much more widespread. It came into prominence via model/actress/celeb spouse Alana Hamilton Stewart.

Aaron is a name of subtle contrasts: an unusual spelling that is easily recognizable; a solid Biblical choice that doesn’t feel exclusively tied to religion; a well-established name for boys but sometimes confused with the girls’ name, Erin; used internationally but with notably different pronunciations; classic like Andrew but not out of place with recent favorites like Weston or Jayden.

Lauren was derived from Laurence, an English name from the Roman family name Laurentius, meaning "from Laurentum." Laurentum, an ancient Italian city, got its name from the Latin word laurus, meaning "bay laurel."

Nadia, an accessible Slavic favorite, has a strong run of popularity in the US in the early 2000s, partially thanks to the character on Lost called Nadia but actually named Noor, but it's since slumped down the rankings. An earlier inspiration was Romanian gymnast Nadia Comaneci, who won the 1976 Olympics.

Connor, the appealing name of an early semi-legendary king of Ulster in Irish mythology, sits firmly in the Top 100 and taken together with its alternate spellings would rank even higher. In its native Ireland the Conor version is one of the highest charting boys’ name.

The name of the sainted mother of the Virgin Mary was among the top girls’ names for centuries, in both the original English Ann spelling and the French Anne. Both left the Top 100 around 1970 but Anne is still among the most classic names for girls, although others are more likely to choose the original Hannah, the Anna variation, or even Annabel or Annabella.

This flower name was one of the most popular in her class in the seventies and eighties, a fact reflected in the 1989 movie Heathers, in which every snobby girl in the high school clique bears the name. Now, though still pretty and evocative of the Scottish moors, it has faded in favor of other purplish blooms. It fell out of the Top 1000 in 2016 after having been as high as Number 3 in 1975, when it was given to close to 25,000 girls. Across the pond in the UK however, it remains near the latter end of the Top 1000.

As a highly popular girls' name in all Spanish-speaking countries, this saintly Latin variation of Mary retains a timeless beauty. Through the centuries, Maria remains one of the most widely-used girl names starting with M.
