Ideas for the Twins

Holly ranks just in British Top 50, but it's been out of favor here since the 1970s Era of Nickname Names. Still, the name may be on her way back as a rejuvenated nature pick.

Lilou is a charming, rarely heard import. Occitan is a language spoken in Provence, in the south of France, in which the suffix "ou" denotes a pet form — thus, Lilou as a short form of Liliane or its Occitan form Liliana or Liliano. Its popularity in France--where it's currently Number 12--can be traced to the 1997 film The Fifth Element.

A versatile classic, Lucy is both sweet and solid, a saint's name, and the heroine of several great novels. First fashionable in England and Wales, Lucy is now a popular choice in the US, The Netherlands, and New Zealand.

With the success of all names Max, from Max itself to Maxwell to Maxfield to Maximilian, it's just possible that Maxine could be lured away from her mah-jongg game at the clubhouse and into the nursery. She's already been chosen by hip musician Nick Hexum for his daughter, sister to Echo.

Combining the mild and the innocent, this sweet and feminine name is worthy of a comeback, in the mode of Madeline and Cecilia. Its original, also attractive form is Melisende, which came from Germany to France and was borne by a daughter of Charlemagne.

Millie is back. It's a Top 100 name throughout much of the English-speaking world, though not yet in the US. Millicent would be an appealing long form, but many people are using Millie all by its cute self -- so many, in fact, that it returned to the Top 500 in 2015 for the first time since World War 2 and continues to climb.

Sweet, nicknamey name belonging to the tragic heroines of both La Bohème and Rent. Mimi might feel too slight for many parents to use on the birth certificate, but as a short form, it's one of the cutest of the cute baby names.

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.

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.

Ottilie is trending in the UK, where the pronounced T helps the name sound pretty and delicate, ala Amelie. Ottilie is less popular in the US, where many Americans pronounce it as a near-homonym for "oddly".

Piper is a bright, musical name that entered the list in 1999, one year after the debut of the TV series Charmed, which featured a Piper, and it's been a consistent riser since. Piper Kerman is the memoirist whose prison experiences provided the basis for the hit Netflix series Orange is the New Black.

Quinn is the Anglicized version of the Irish patronymic surname Ó Cuinn, meaning "descendent of Conn." Conn has two possible derivations—the Old Irish cond, meaning "intellect," or cenn, meaning "chief." One of the most notable Quinn clans was from County Tyrone in Northern Ireland.

From the first time we saw the name Saskia attached to a portrait of Rembrandt's wife (her full name was Saakje van Uylenburgh, but she was always called Saskia), we have found it utterly charming and wondered why it hasn't attracted more fans In this country--she's appreciated by the Brits, who have moved her to Number 392. Saskia is one of those names that's been used in Europe since the Middle Ages, but has never crossed the ocean.

The temperature is definitely rising for this popular seasonal name, which began being used in the seventies, and has been heard consistently ever since.

This pet form of such names as Winifred and Edwina and Gwendolyn has loads of vintage charm, a la Millie and Maisie, with a decidedly winning vibe. And it just got celebrity cred as the baby daughter of Jimmy Fallon.
