Susannah is by far the most stylish form of the classic name now that Susan and Suzanne have retired. Susannah has biblical and musical pedigrees, is impervious to trends, and has an irresistible, flowing rhythm. It can be spelled just as properly with or without the final 'h.'

Like Joanne and Christine, middle-aged Diane has been overshadowed by the a-ending version of her name. Diane has a definite mid-century feel; it was a Top 20 name from 1946 to 1959. Though it has several distinguished bearers, including Dianes Sawyer, Keaton, von Furstenberg, Lane, Arbus, Kruger and Farr, it fell off the Top 1000 in 2004 and last year was given to about 60 baby girls, the same number as Dillon and Eugenia.

This feminization of Anthony, like other early French forms, such as Babette and Nanette, is not heard as often as it once was, but it could be time for a reappraisal of this delicate Gallic choice.

This spelling of Jillian is now much more popular than the original, maybe because the G version invites pronunciation problems.

Widely used here since the 50s, Allison — a derivative of Alice — has now been once again surpassed by the original Alice as parents embrace vintage revivals. Despite this, Allison's popularity has slipped only slightly.

A long-integrated French feminine form of Adrian, now overshadowed by the a-ending version, but still a valid option, with considerable substance and dignity—though these days more parents would probably choose Adriana.

Leila was popularized in the West by the poet Byron, who used it in his poem Don Juan for a ten-year-old Turkish girl. Leila also appears as a fairy in the Gilbert & Sullivan comic opera Iolanthe.

Kyle is stronger and sharper, though many parents will prefer the more distinctly feminine Kyla for their daughters. Kyla may owe much of its popularity to trendy cousin Kayla.

Bethany is a lyrical name that still strikes many parents as a fresher, more substantial substitute for the overused Brittany/Brittney or the more antiquated Beth.

Aisling is currently a very popular Irish name for girls. Pronounced variously as ASH-ling, ASH-lin or ash-LEEN, it was part of the revival of authentic Irish names in the twentieth century, and is now being sparingly used by U.S. parents in place of the dated Ashley--though often spelled phonetically as Ashlyn or Ashlynn.

One of those names that's suddenly on the map because of a celebrity's influence, Leighton Meester of the TV show Gossip Girl. She pronounces it LAY-ton but some will intuitively say LEE-ton.

Carina is a pretty delicately feminine name whose fall from popularity is not helped by its similarity to hurricane name Katrina or slang victim Karen.

Popular in France in the 60s, Marielle is one of many international variations and diminutives of Mary. While actress and author Mariel Hemingway made us aware of the more abbreviated spelling — which is currently the more popular option in the US — this longer, elegant form saw increased interest in a recent year, when it was chosen for 115 girls.

Adalyn is one of a large group of Ad-beginning names for girls, which include Adeline and Adalynn and Adelaide and Addison — essentially, anything leading to the popular nickname Addie is in.

Adalyn entered the charts in 2007 and rose quickly, but has been fairly steady in the mid 100s for nearly 10 years now.

Mackenzie begat McKenna - a catchy but very trendy choice. While the Mc or Mac prefix means "son of," this is much more popular as a girl name in the US, peaking at #177 in 2002.

The sleek Malin is a contracted form of Magdalene or Madeleine, used in Sweden, Norway, and Switzerland. A popular choice back in the 2000s, it has declined in popularity in recent years, but it remains a concise and appealing choice.

Once a Top 100 name, this Spanish diminutive of Ana still retains some of her Latin flair. A notable namesake is noted attorney Anita Hill, another is the great jazz singer Anita O'Day. Plus there's Disney cred via the lead human character in 101 Dalmatians.

The name of the wife of Alexander the Great, more attractive than the better-known Roxanne. Roxana was first used in the English-speaking world in the 1600s and was popularized by Daniel Defoe's novel Roxana, published in 1724. An underused and attractive possibility and perfect if you're searching for names that mean new beginnings.

Jessamine, a charming name occasionally heard in England, is just beginning to be appreciated in the U.S. as a possible successor to all the Jess names of the past. It's also spelled Jessamyn, as in Quaker novelist Jessamyn West, author of Friendly Persuasion--who started life with Jessamyn as her middle name.
