Ellie first took off in the UK—yes, in this nickname form—and this warm and friendly name has also become hugely popular here. In 2011, Ellie entered the US Top 100 girl names for the first time and has remained near the top of the charts ever since.

Elliot (which boasts several spellings depending upon how many 'l's or 't's you want to use) is a winner -- it has the ideal quality of being neither too common nor weirdly unique. Elliot had a style boost back in the early 1980s via the young hero of the movie E.T. , who was named Elliott. Since then there have been Elliots on Law & Order: SVU and Mad Men.

Strong but sweet, Leah is a classic name that doesn't feel dull or dusty. It's got plenty of dignity, grace, and pluck, making it a solid choice in the 21st century.

Sarah was derived from the Hebrew word sarah, meaning "princess." Sarah is an Old Testament name — she was the wife of Abraham and mother of Isaac. According to the Book of Genesis, Sarah was originally called Sarai, but had her name changed by God to the more auspicious Sarah when she was 90 years old.

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.

Cosy and warm but with plenty of substance and strength, Tess is a literary diminutive that works perfectly well as a stand-alone name. Stylish in the Netherlands, it currently sits outside the Top 1000 in the US, where Tessa and Teresa are currently preferred.

Adam -- a primal Old Testament name -- was revived as a 1960s cowboy name. Adam is not as popular as it once was and feels ready for a respite, replaced by newer A names like Aidan/Aiden, Avery and Axel. Its most prominent current bearers include Adams Sandler, Levine, Brody and Driver -- who plays a character named Adam on Girls.

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."

Paul is an ancient name for boys -- popular in Roman and medieval times -- that's not very fashionable now, which can work in its favor, scarcity balancing simplicity.

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.

Alfred is up off his recliner! If you're looking for a path to Fred, you can go directly to Frederick or take the long way around with the so-out-it's-in-again Alfred. Alfred is quite popular in several European countries, especially England and Wales, Norway, Sweden, and Denmark.

King David's father turned 1980s cowboy, Jesse is now down in popularity but still a Biblical classic, ranking in the US Top 1000 for its entire history. The name is associated with a wide variety of bearers, from outlaw Jesse James to Olympic athlete Jesse Owens to activist Jesse Jackson to current actors Jesse Tyler Ferguson and Jesse Eisenberg. The spelling Jesse is more usual as a boys' name while Jessie is more traditional for girls.

Jonas has a slightly more grandfatherly image than the English version of his name, but that only adds to its retro appeal. And though it may lag behind Jonah in this country, Jonas is riding a huge wave of popularity in Europe, where it ranks highly in Germany, Switzerland, Austria and Norway.

Elvis naming his daughter Lisa Marie and Nat King Cole's hit song "Mona Lisa" conspired to catapult one of Elizabeth's many offshoots to a high of #4 in 1970.

Ben, the diminutive of Benjamin or Benedict, can easily stand on its own as a simple, strong, nice-guy choice, though it's somewhat attenuated. Ben is this generation's Bob or Bill.

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.

Sara, the streamlined form of Sarah, makes this ancient name feel more modern, but perhaps a bit lighter weight.

Lilly may contain one L too many for some people, though this secondary spelling of a name that's become wildly popular is still a popular choice. And the Lilly spelling does feel a bit less wispy, a bit more like a name as opposed to a mere flower, than the slender and delicate Lily. Lilly suggests the long-form Lillian, but it doesn't need to be an abbreviation for anything; Lilly can stand on its own.
