Old-Fashioned, Vintage, Retro, Classic, Eclectic, Unusual and Uncommon Names for Girls

With Tillie a new favorite of avant-garde parents, the British music-hall Tessie might conceivably follow.

A paramour of Alexander the Great and the heroine of a Jules Massenet opera based on the life of a fourth century Egyptian saint, this name is nothing if not dramatic. Often spelled with a diaeresis or umlaut -- aka two dots -- over the letter i, Thais is a Top 100 girls' name in France and is also popular in Spain. 

Thalia was one of the Three Graces in Greek mythology, and also the Muse of comedy and pastoral poetry, making this a Hellenic choice worthy of consideration.

Deriving from the ancient Greek name, Theokleia, Thekla is a contracted form that appears in the New Testament. According to the Acts of Paul, Thekla (or Thecla) is a 1st century saint and the first virgin martyr who angers her mother and her suitor by vowing to remain chaste after hearing Paul speak.

Though modern parents seeking to honor an ancestor named Thelma might opt for the airier Thea instead, Thelma is starting to make its way back onto adventurous vintage name lovers' radars. It is currently experiencing a modest revival in France, where it now ranks around the #300 mark.

Theodora is one of the most revival-worthy of the charmingly old-fashioned Victorian valentine names, softly evocative but still substantial, as is the reversed-syllable Dorothea.

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. Vice President Aaron Burr named a daughter Theodosia ("Dear Theodosia" is a song in the smash musical Hamilton), and it was the birth name of silent screen vamp Theda Bara. Theodosia actually appeared on the US popularity lists in the 1880s and 90s.

This ancient name, belonging to a Byzantine empress, may be difficult to wear. The English variation Tiffany may be more wearable.

Feminine form of Theophilus

The popular appeal of the strong, intelligent Saint Teresa of Avila, combined with the selfless compassion of the more recent Mother Teresa, have fused to give this second-tier classic a somewhat noble, religious image. Although the origins of the name are uncertain, it has been prevalent particularly in forms Theresa, Teresa, and Therese throughout Europe for centuries.

Though rarely used now that many parents would rather appropriate men's names than sweeten them with feminine endings, Thomasina does have some vintage appeal.

Cute and unusual as a nickname, but lacking the legs to stand on its own.

A surprise recent hit revival with cutting-edge British, Tribeca and Malibu parents; Tillie, also spelled Tilly, is cute, frilly, and sassy all at once. Tilly is currently Number 90 on the England-Wales popularity list, joining such other Top 100 nickname names as Milly, Maisie, Kitty and Lottie. Tillie along with these other short forms transform proper names rooted in other cultures into true English names for girls.

A favorite in England and Wales where nicknames as given names are very much the norm, Tilly has the potential to catch on in the US, given its similarity to the popular Lily and Ellie and the rising stars Millie, Billie, Kallie, and Nellie.
