Elva is a multicultural choice, being both an anglicization of the Irish Ailbhe and an feminine form of the name Alf, meaning "elf". Popular in the US at the beginning of the 20th century, it remained in the charts until the 1970s before falling out of favor.

Annika is a surprise hit of recent years, inspired by golfer Sorenstam; for Trekkies, it was also the name of a 'Star Trek:Voyager' character. Some people's first memory of it might be as Pippi Longstocking's friend. A nice namesake for an ancestral Ann.

Unusual and lush Roman name adopted, improbably, by the Puritans.

Sweet but sleek, and distinctive, Liesel is an old German nickname-name for Elisabeth. It might have once seemed inextricably tied to to its country of origin, but now, like Elsa, Enzo, Saoirse, Freya, Soren, and Heidi, it leans more towards being international and European chic.

In ancient Rome, Cornelia was considered the paragon of womanly virtue, making it a handsome name with an excellent pedigree. It's rare today, so if you want a name no one else is using, somewhat reminiscent of Amelia and the Shakespearean Cordelia, Cornelia should be on your list. Cornelia's short forms might include Cora, Nelia or Nell--anything but Corny.

If you love both unique baby names and flower names for girls, Amaryllis might be a perfect choice for you.

The original but less common spelling of Sybil, this name comes from Greek and Roman mythology, in which the sibyls were female prophets. A name that has dipped in and out of style since the Middle Ages, the rise of the lovely Lady Sybil Crawley on television's Downton Abbey may shine a light on this mythological name.

Endellion is the name of an early saint who was a daughter of King Brychan and goddaughter of King Arthur whose life is commemorated by the Cornish village of St. Endellion.

State name Alaska stems from an Aleutian word for the land mass itself. The number of baby girls named Alaska has doubled in the past five years, and is sure to continue increasing as more place names are annexed as baby names. Wilder but as habitable as Dakota or Cheyenne, Alaska is a girls' name choice for the future.

Less known than other Cornish beauties like Demelza, Elowen and Kerensa, Elestren is a pretty Cornish botanical name ripe for wider usage.

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.

This feminine form of Theodosius has long been buried deep in the attic, but might be a good discovery for the parent who wants to move beyond Theodora.

Theodosia actually appeared on the US popularity lists in the 1880s and 90s.

Exie is a vintage feminine name that enjoyed modest popularity in the United States during the late 19th and early 20th centuries. Often used as a nickname for names beginning with 'Ex-' or as a diminutive for Elizabeth or Exilda, it has a quaint, old-fashioned charm. The name nearly disappeared from usage by the mid-20th century, making it extremely rare today. Its brevity and distinctive sound give it potential appeal to modern parents seeking truly uncommon vintage names. Exie has Southern American associations, as it appeared more frequently in Southern states during its peak usage. The name's simplicity and unique 'x' sound offer a combination of antique appeal and contemporary phonetic interest.

Calista Flockhart may have made her variation of this beautiful Greek name familiar to modern Americans, but the even-edgier x version was the name of an earlier feminist heroine: a character in Kate Chopin's The Storm.
