Though greatly overshadowed by the trendy Olivia, Olive has a quiet, subtle appeal of its own -- and is now enjoying a remarkable comeback. Olive is one of only four girl names starting with O on the US Top 1000. Cool couple Isla Fisher and Sacha Baron Cohen chose it for their daughter, reviving the name to stylishness, and now Drew Barrymore has a little Olive too, as has country singer Jake Owen.

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.

The luminous Ingrid Bergman's appeal was strong enough to lend universal charisma to this classic Scandinavian name, which has been somewhat neglected in the US. Even today, a child named Ingrid would be assumed to be of Scandinavian ancestry, signaling the name has never been fully integrated into the English lexicon the way other European choices from the same era like Danielle or Kathleen have.

Frances, a soft and gentle classic last popular a hundred years ago, is trending again. The cool nickname Frankie is one reason for the revival of Frances, adding lightness and sass to a serious name. Frances is the feminine form of Francis, the English variation of the Latin name Franciscus. Franciscus, meaning "Frenchman," was taken from the Germanic tribe the Franks, which got its name from the francisca, the axe they used in battle. Until the seventeenth century, the spellings Frances and Francis were used interchangeably for both sexes.

Rupert is a charming-yet-manly name long more popular in Britain (where it's attached to a beloved cartoon bear) than in the U.S. Yet we can see Rupert as a more stylish, modern way to honor an ancestral Robert.

You might think of Harper as the hottest name of the last decade, jumping from obscurity to the Top 10, where it remained until last year.

Amos is a robust biblical name that's being discovered by a new generation of parents in a major way. Similar to other popular choices like Amias, Asa, Moses, and Thomas, it has a contemporary air with plenty of history.

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.

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.

The independent Alex has become a classic in its own right. One of the truest unisex names, Alex is used almost equally for both sexes. Alex is used both on its own and as a short form of formal names of both genders, such as Alexander, Alexandra, and Alexis.

This name of three early popes has been associated in recent years with a cocky cartoon cat ("Thufferin' thuccatash!") and the Italian Stallion hero of the Rocky and Rambo movies (who was born Michael) — and yet we think it just might be ready to move further back into the mainstream.

Amity--what nicer gift to give your little girl than a name that signifies friendship and harmony? This virtue name is also more rhythmic and feminine than the single-syllable Hope, Faith, and Grace.

A name that has a bit of a shouldn't-I-be-a-middle-name sound, though still in use as a first for both genders. Lee might be a good choice if you want something that sounds at once traditional yet modern, unisex but not newly-minted.

Keegan is one of a clan of spirited Irish surnames starting with K and ending with 'n'--this one with the cheery double 'e' in the middle-- that are appealing to an increasing number of parents. It derives from Mac Aodhagáin, meaning "son (or descendant) of Aodhagán," a diminutive of the Irish name Aodh--pronounced Aye.

Maple is one of those sweet-spot word names that sounds so almost name-like that it doesn't feel outlandish or strange, despite its relative newness as a given name. Just as Juniper is adjacent to June or Pippa, Clover like Chloe or Clara and Ember like Emma or Ebba, Maple is enough like Mabel, Maisie and Mae that it blends in well and has a touch of borrowed vintage charm.

Kathleen is the early Irish import version that came between Katherine and Kaitlin, and which hasn't been used in so long it's almost beginning to sound fresh again. It was a surprise pick by one of the hip Dixie Chicks, Martie Maguire. Kathleen was a Top 10 name from 1948 to 1951, and it is the subject of several old sentimental songs, such as "I'll Take You Home Again, Kathleen."

The seventh most common surname in Scotland, once associated only with soup, is now being considered as a last-name-first choice, accessible but unusual.

Effortlessly cool with a hint of the mystical, Phoenix rolls a lot of trends into one: it's a place-name and a bird name, it ends in the stylish letter x, it's got in-built nicknames, and it's unisex too. Familiar but not over-popular, Phoenix ranks in the US and UK Top 1000s.

Though this feels like a modern invention, Jay has been in use for centuries. Early Jays often were named in honor of founding father John Jay, whose surname derived from the jaybird. A popular mid-century choice, Jay was in the Top 100 from 1956 to 1970. In the last couple of decades he was replaced by such more elaborate forms as Jayden, Jaylen, and Jayce. But Jay could make a comeback in tandem with cousins May, Kay, Fay, and Ray.

Actor Joaquin Phoenix (brother of River, Rain, Liberty and Summer) highlighted this one, then Kelly Ripa began talking about younger son Joaquin on her daily TV show, and presto—it's now one of the hottest and most appealing multicultural baby boy names.
