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.

Thanks to its dashing Anglo-Irish image — due partly to Colins Firth and Farrell — and its C-initialed two-syllable sound, Colin and its cousin Collin have enjoyed a long run of popularity, reaching as high as Number 84 in 2004.

Samuel has been so popular for so long that it's hard to believe it's still climbing, at its highest point since the 1890s.

During its Top 10 heyday in the late 90s and early oughts, Andrew was one of the "cooler" classic boy names, an update on the old guard Roberts and Richards.

Tristan -- known through medieval legend and Wagnerian opera -- has a slightly wistful, touching air. This, combined with the name's popular "an" ending, makes Tristan very appealing to parents seeking a more original alternative to Christian.

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.

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.

Isabella has been a Top 10 name for girls in the US for two decades now. The Latinate form of Isabel, a variation of Elizabeth which originally derived from the Hebrew name Elisheba, Isabella reigned as Number 1 in 2009 and 2010.

The ubiquitous French version of Mary came into the English-speaking world in the nineteenth century. In the United States, Marie was a huge hit at the turn of the last century and for the ensuing fifty years, becoming the seventh most popular name in the country for three years, from 1901 to 1904.

Miranda, a shimmeringly lovely, poetic name that was invented by Shakespeare for the beautiful and admirable young heroine of his play, The Tempest, is still a recommended choice even though its popularity peaked in the 1990's, partially as an antidote to Amanda. But while Amanda now sounds dated, Miranda retains a good measure of its charm.

Diana, the tragic British princess, inspired many fashions, but strangely, not one for her name. For us, Diana is a gorgeous and still-underused choice.

Heidi became known — and popular — via the 1880 eponymous children's classic by Swiss writer Johanna Spyri and, despite decades of American Heidis of all sizes, shapes, and personalities, the name seems permanently tethered to that spunky little girl on the Alpine mountaintop in the book and Shirley Temple movie.

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.

This old Scottish form of Helen has had quite a history, going from appearing as one of the shining heroines of the Arthurian legends, the princess who fell in love with Sir Lancelot and became the mother of Sir Galahad, referred to as 'Elaine the fair' and 'Elaine the lovable', to being the name of the most famous of New York's celebrity restaurants, to being the archetypal New York neurotic on Seinfeld.

Michael was the Number 1 American boys' name for almost half a century. While Michael has moved out of the Top 10 baby boy names, it's still widely used.

Spencer is a name that has everything: it's both distinguished sounding and accessible, dignified but Spencer Tracy-like friendly. Picked by several celebrities (a couple of times even for a girl), adding up to an enthusiastically recommended choice.

Mark has the rare appeal of a strong, sleek name with a minimalist modern feel and ancient roots. The name Mark is taken from the Roman god of war Mars, also the namesake of the planet.

Roman is an ancient name trending in a major way. A surprise hit name of recent years, Roman now ranks in the Top 100 not only in the US but throughout the English-speaking world, and is rising in other European countries as well.

Michelle is the feminine form of Michel, the French variation of Michael. Michael was derived from the Hebrew name Mihka’el, meaning "who is like God." The alternate spelling Michele, with one "L," was the original version of the name. Michelle appeared as a later Anglicization in the 20th century.

Mary is the English form of Maria, which ultimately was derived from the Hebrew name Maryam/Mariam. The original meaning of Maryam is uncertain, but theories include "drop of the sea" (from Hebrew roots mar "drop" and yam "sea"); "bitter" (from Hebrew marah "bitterness"); and "beloved" (from the Egyptian root mr).
