The Considerables (girl)

A strong Greek name with pan-European charm, Petra is a relatively recent feminization of Peter, though it relates back to an incredible ancient city in Jordan that was rediscovered in the early nineteenth century.

This name of a tragic figure in Greek mythology, the daughter of King Minos, sister of Ariadne and wife of Theseus, has a mysterious and intriguing appeal, and would make a dramatic choice.

The fact that this Spanish classic, which honors the Virgin Mary, does not end in the conventional letter 'a' gives it a special sense of strength, elegance, and style, making it a worthy choice.

This slightly more compact version of Sabina has ties to France and Germany. Unlike its sister name, Sabine has never charted in the United States Top 1000. Today, both names are given to roughly the same number of baby girls in the US, about 70 each year.

Signe could make an offbeat, more unusual alternative to Sydney or Sigrid. In Norse mythology, Signe was the twin sister of Sigmund. Can also be spelled Signy.

Sigrid is a distinctly Scandinavian name that is starting to edge out into the wider world, a la cousin Ingrid. Unfortunately, short form Siri is now off the table, but Sigrid is still a possibility.

The musical, sylvan Sylvia seems poised to join former friends Frances and Beatrice and Dorothy back in the nursery.

Although Sylvia seems to be having somewhat of a revival among trendsetting baby namers, we'd still opt for the even gentler and more unusual Sylvie. Despite being dated in its native France (where it was popular during the 1950s and 60s), in English-speaking regions it still feels fresh and international without being unfamiliar and has a cosmopolitan, international air. It debuted on the US Top 1000 in 2016.

Thisbe, the name of a beautiful but tragic lover in mythology, is lively and cute -- in a slightly thistly, prickly way. Ovid retold the story of Thisbe and Pyramus, young lovers in ancient Babylon kept apart by family rivalry, which was the inspiration for Romeo and Juliet. A modern bearer of the name is writer Thisbe Nissen.

In Sarah Dessen's novel Along for the Ride, the baby daughter is named Thisby, nn Isby.

Variation of Isolde, the name of a great Celtic heroine. The mononymous French singer Yseult is the most notable bearer today.
