Once a poetic Celtic name, that of the angel who governs the month of June, Muriel became the mom or grandma on TV sitcoms. A Top 200 name from 1912 to 1933, Muriel may be due for a comeback according to our Hundred Year Rule. Only 50 baby girls were given the name in the US last year, and none were given Muriel's French variation, Murielle.

Almost as popular in the 1950s among the Irish in Boston as it was with those back in Bray, Maureen was once among the most prominent Irish names for girls in the US but has fallen from favor along with most of her een-ending sisters such as Eileen and Colleen.

Alaina, part Alana and part Elena and maybe also a little bit Elaine, is one of the many feminine forms of Alan (or its French form Alain) that have grown in popularity over recent decades, surpassing the male original.

A strong, straightforward Irish unisex surname, with a merry glint in its eye, Reagan has been leaping up the popularity lists, to become one of the top girl names starting with R. Some will inevitably link it to President Ronald, but spell it Regan and it's a Shakespearean name: a daughter of King Lear.

Ailbhe is a unisex Irish name that has appeared throughout Irish history, borne by a 6th-century (male) saint, and by a female warrior of Fianna, a legendary group of women warriors, led by Fionn MacCumhaill. Today, the name is predominantly used for girls, likely because it sounds similar to Alma, Ava, and Alba.

Irish Aileen and Scottish Eileen may be pronounced the same way or Aileen can be pronounced with a long a at the beginning. While neither is particularly stylish, Aileen is slightly more popular and has reversed its downward slide to inch upward in the past few years, perhaps thanks to its stylish A beginning. Nicknames for Aileen include Isla, Ayla, Lee and Lena.

Familiar in the US thanks to the lovely movie Brooklyn, based on the Colm Toibin novel of the same name. Popular in medieval times, it is still used in Ireland (properly spelt with a fada: Eilís) could make an alternative to the super-popular Isla. Eilish and Eibhlis are alternate forms.

While the male Alva or Alvah relates directly to the minor Biblical character, the female version is more likely an Anglicized form of the Irish name Ailbhe, or a feminine form the name Alf (and Alf- beginning names), popular in its native Sweden and Norway. Best known as Thomas Edison's middle name, Alva has true unisex roots.

A huge name in the late 90's and most of the 00's, Kaitlyn's been on a downward trend in recent years. Kaitlyn and its soundalikes have been so well used in the US that they can no longer be seen as fresh, but it's still relatively popular in Canada.

A name with a bit of glamor but also cowgirl vibes, Dallas entered the US Top 1000 for girls in 1992. It fell out of style during noughties, but reappeared in 2012 when other gender neutral names like River, Sawyer, Rowan, and Blake were also climbing fast.

This ultrapopular boys' name is rapidly becoming a hot name for girls; admired for its buoyant Irish spirit.

A popular Irish name virtually unknown here, but one that feels like it could follow in the footsteps of Siobhan and Saoirse. It's pronounced SOR-ka, but with a little hiccup between the 'r' and the 'c' that's difficult for non-Gaelic speakers to reproduce. Spelled (and pronounced) Sorsha, she is a major character in the movie Willow.

This attractive and unique Scottish form of Alice can also be found in the spelling Aileas. Like Alice, it ultimately derives from the Germanic name Adalheidis. Spelt with the fada, Ailís, it's Irish and pronounced with a longer final vowel: AY-leesh.
