This endearing nickname name is one Katherine pet form that predates all the Kathys and Katies, having been fairly common in the eighteenth century. With the current mini-craze for animal-related names, Kitty is sounding cute and cuddly again—she's already jumped back onto the U.K. list, at number 199.

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.'

Cute Gracie is one of the more recently revived nickname names by parents who chose it over the more formal Grace--or variations like Graziella or Grania. Country singers Faith Hill and Tim McGraw cut straight to the nickname when they called one of their daughters Gracie, and actors Ron Livingston and Rosemarie DeWitt named their newborn daughter Gracie James. Gracie Gold is a popular young figure skater.

Posie and its near-identical twins Posy and Posey are delicate old-fashioned flower names of the type that are stylish today: Think Poppy, Marigold, Clover.

Could Lilac be the next Lila or Lily or Violet? It certainly has a lot going for it--those lilting double 'l's, the fabulous fragrance it exudes, and the fact that it's a color name as well, providing a ready made nursery theme. In addition, the lilac is symbolic of first love.

Sweet, enchanting Lilou is considered both a pet name from the Occitan language (spoken in Provence in the south of France), and a compound name, blending floral Lili with classic Louise. It peaked in France back in 2009 when it reached #12, and while it has now fallen in popularity, it remains in the Top 200.

Lula is one of the livelier nickname-names with the fashionable double-L sound: It joins Lulu, Lila, Lily, and Lou among the trendiest names today. Lula might be short for Talula and sisters or for Lucy or Louise, or may stand on its own two adorable feet. Lula was actually a Top 50 name in the late 1880's and continued in the Top 100 for a couple of decades more.

Liv combines the succinct charm of a nickname—people might assume it's short for Olivia—with the solidity of being a classic stand-alone Scandinavian name with a life-force meaning. It was brought into the public eye (in the English speaking world that is) due to the fame of actress and Aerosmith daughter Liv Tyler.

A sweet, nostalgic nosegay kind of name, Posy has been long fashionable in England, a country of gardeners, but this pretty bouquet-of-flowers name is still rarely heard in the US, though it could be seen as a more unusual possible alternative to Rosy or Josie.

Through all the years when Betty, Betsy, Beth, Liz, and Lizzie were the Elizabethan nicknames of choice, the bubblier Libby was set aside, but today it may be the most modern of all—it has already made a strong comeback in England and Wales, where it ranks Number 139.

Susanna is an old and under-appreciated name, perhaps because of the recent overpopularity of Susan, that is certainly due for a comeback.

The longer Isabella stays in the Top 10—and it's been there for more than a decade—the more we hear the nickname Izzy (especially if we watch Grey's Anatomy). it's just a matter of time before it stands on its own, as it has as a first name for the daughter of Eddie Murphy and Paige Butcher.

Like the masculine form Galileo, Galilea is a variant of Galilee, a region in Northern Israel of great Biblical significance. Given the current popularity of soft Italian girls’ names, this name’s long historical roots, its beautiful sound and the potential for cute nicknames (Leia, Lil, Ally, etc) it’s no surprise that this name has been on the rise in recent years.

A cute, zippy French saint's name that's picking up in popularity there, and starting to in the US as well. Zélie originated as a short form of Azélie, thought to derive from Adelaide via the Occitan form Azalaïs. Saint Zélie was born Marie-Azélie.

Liliosa, one of the most extravagant forms of the ever-more-popular and varied Lily family, is an ancient saint's name that's a perfect candidate for revival by parents who love the double-L flower name trend but want a distinctive variation. Saint Liliosa was one of the martyrs of 9th century Cordoba, along with her husband Felix and cousins Aurelius and Natalia — all names newly fashionable in the modern world.

This romantic, ethereal name sounds straight out of Arthurian legend but is in fact a modern hybrid of Guinevere and Lili.

Lizzy is a feminine name primarily used as an affectionate diminutive of Elizabeth, which has Hebrew origins meaning 'God is my oath' or 'pledged to God.' This friendly, approachable nickname gained independent usage in the 19th century and continues to be chosen as a standalone name today. Lizzy projects a youthful, spirited, and warm personality while maintaining connections to the regal history of Elizabeth. The name enjoyed renewed popularity in the late 20th and early 21st centuries as parents increasingly chose shorter, less formal names for their daughters. Cultural references like Pride and Prejudice's Lizzy Bennet have contributed to the name's enduring charm and appeal.

Milly and her more popular sister Millie are adorable Old Lady nickname-names springing back to life. Nearly 100 baby girls were named Milly, just Milly, last year, and Millie is in the US Top 500. Milly is the Molly of the new generation.

A cute nickname, but June is a much better bet for the birth certificate.

Lillemor is a relatively recent coinage in Scandinavia, where it was most popular in the 1930s and '40s, especially in Sweden. As such, it is considered rather dated in Scandinavia, but it would certainly make a fresh choice for lovers of "Lily" names abroad — although the "Lil" in this case actually comes from lille "little".
