Beatle girls

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.

Molly is one of the original nickname names, ALWAYS ranking among the US Top 500 girl names since statistics began, in 1880. Molly peaked in 1991 only to rise just as high again in 2011, and though softening retains a good measure of popularity and charm.

To some, Nancy is a sweet, sparkly, vintage choice with plenty of energy and style. For it strays too much into '"old-lady" territory to be cool again yet. It's out of fashion in France, New Zealand, and Canada; it lingers towards to bottom of the US charts. In the UK however, Nancy has been a Top 100 name for nearly a decade where it fits right in with Evie, Mabel, and Pippa.

This mild-mannered short form was Queen of the Prom in the fifties and sixties, but today is mostly heard on TV's The Office (and of course as one of the founders of Nameberry).

Penelope is an unlikely 21st century baby name success story. Off the Top 1000 for 25 years, Penelope jumped back on in 2001 and has been heading uphill ever since, propelled by the trend for mythological names, Spanish actress Penelope Cruz, and some high-profile celebrity babies.

Like Peggy and Patsy, the kind of zesty moniker young Judy Garland would sport in her early let's-put-on-a-show flicks. It fell out of favor (and the Top 1000) for a while, but has recently rebounded by reentering the charts in 2013. Expect it to continue gaining traction as a result of surprise hit Penelope.

Prudence, like Hope and Faith, is a Puritan virtue name with a quiet charm and sensitivity that is slowly returning to favor, though it hasn't yet registered on the charts.

One of the glamour girl names of the Rita Hayworth 1940s, Rita was once a Top 50 name and stayed on the SSA list until 2002.

Sadie started as a nickname for Sarah, but their images couldn't be more disparate. Where Sarah is serious and sweet, Sadie is full of sass and fun.

Sally is a cheerful, fresh-faced girl-next-door name that was originally a nickname for Sarah, but has long been used independently. Sally was popular in the eighteenth century and then again from the 1920s to the 1960s--it was just outside the Top 50 around 1940. Though it hasn't been heard as a baby name for decades, we can see Sally bouncing back, especially after her exposure as young Ms. Draper on Mad Men--the Nameberries rank it at Number 621, and it's a Top 100 name in Sweden.

Stella is a name with star quality and sparkle, that manages to sound both ethereal and earthy. Celestial but not otherworldly, it lands somewhere between the popular Ella and bold Seraphina.

Sunshine was seen as a quintessential hippie name of the 70s, reaching as high as Number 536 in 1975. Now such names are making a bit of a retro comeback, seen, for example, as a character on Glee.

The name of a martyred medieval saint, Valerie has been on the popularity list since its earliest publication in 1880. Though it peaked in the 1960s, remaining in the Top 100 until 1988, it still doesn't sound terminally dated; the association with the word valor gives it a sense of boldness and makes it one of the special group of girl names that mean strong.
