Under-used and Under-appreciated Girls' Names

Philomena is an earthy Greek name now used in various Latin countries. While it has felt simply clunky for many years, it's starting -- along with such sister names as Wilhelmina and Frederica -- to sound so clunky it's cool.

A quaint and quirky flower name, until recently considered a bit too prim for most American classrooms but brought back to life in recent years by the attractive character of Primrose "Prim" Everdeen in the Hunger Games series. In the Top 300 girl names in England and Wales and on Nameberry, Primrose remains rare in the US, but is made more accessible by a raft of sweet nickname options, including Rosie and Posy.

Among a small shower of rain-related names, this pure version can have a cool, refreshing image.

Rebecca is a name representing beauty in the Bible, an Old Testament classic that reached the heights of revived popularity in the seventies but is still a well-used choice. It derives from the Hebrew name Rivkah, from the verb ribbqah, meaning "noose." The biblical Rebecca was the wife of Isaac and the mother of Esau and Jacob. Rebekah was a common spelling of the name in the Bible.

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.

An authentic choice for your little Irish Rose, chosen by singer Sinead O'Connor for her daughter.

Sage is an evocatively fragrant herbal name that also connotes wisdom, giving it a double advantage. It entered the Top 1000 at about the same time for both genders in the early 1990s, but it has pulled ahead for the girls. Toni Collette named her daughter Sage Florence.

Sariah is the perfect compromise name for when you say Sarah, and your spouse says Mariah. Spelled Saria, it's a character in the video game The Legend of Zelda: Ocarina of Time.

Siobhan is the Irish variation of Joan, which is derived from the ancient Anglo-Norman name Jehanne. In this way Siobhan is indirectly related to the name Sinead—the Irish form of Jeannette, which also derived from Jehanne—although Sinead is not a nickname for Siobhan. Siobhan was the name of several early Irish queens and was introduced to the American public by the actress Siobhan McKenna.

Sophia, which was the Number 1 girls' name in the US from 2011 to 2013, is among the top girl names in the Western World, with a sensuous sound and high-minded meaning. A real winner, Sophia reached the top of the charts without losing any—okay, much—of its sophisticated beauty.

Though never as popular as the name of her Bewitched mother, Samantha, Tabitha has its own quirky, magical charm. The name of a charitable woman who was restored to life by Saint Peter in the Bible, it was a popular Puritan choice. Sarah Jessica Parker and Matthew Broderick chose it for one of their twin daughters, which gave it a slight boost. Nonetheless, Tabitha remains in decline.

This Latin word used for evening spiritual services was introduced to baby namers by the Eva Greene character Vesper Lynd in the modern James Bond film Casino Royale in 2006, based on the Ian Fleming novel, and is just now beginning to provoke interest among namers, with its spiritual reference and soft, whispery sound.
