Iolanthe is known primarily through the 1882 Gilbert & Sullivan operetta of that name, in which the title character is a fairy. Iolanthe is a softer version of Yolanda, and is the kind of multi-syllabic classical name once considered too weighty for a modern baby girl, but now within the realm of possibility--this one as a dramatic twist on Violet. The biggest drawback is its variety of legitimate pronunciations in English.

One of the coolest of names, thanks to legendary jazz pianist Thelonious Sphere Monk, who inherited it from his father. It has been used very sparingly since the 1960s--just a sprinkling of baby boys receive the name each year. Monk's middle name Sphere is pretty unique too--a cousin of Cosmos and Cosmo. Some other jazz names to consider: Bix, Ellington, Ella, Etta, Mingus, Dexter and Calloway. :

Despite (or because of) her tragic story in Greek myth--Eurydice was poisoned by a snake and condemned to the underworld, where her husband, musician Orpheus, tried and failed to bring her back--she has provided creative inspiration in the arts, namely as the subject of operas by Monteverdi, Haydn and Gluck, in an eponymous play by Jean Anouilh, and the myth was the inspiration for Tennessee William's drama Orpheus Descending. Paintings by Titian, Rubens and Poussin also focus on Eurydice.

Cyrilla is an obscure feminization of Cyril that's a bit buttoned-up but also intriguingly unique, with an authentic pedigree.

A lively, affectionate Russian pet name that is never given as a full name in its homeland, but has found some popularity in upper-crusty British society.

Is Amora a real name? It made a strong entrance to the US Top 1000 in 2017 so it's one of the Spanish names for girls that is obviously catching on, perhaps thanks to its similarity to Amara, a multicultural name that's achieving widespread popularity here and abroad. Amora sounds like the Latinate amore and is one of the romantic names that mean love, familiar via the classic Dean Martin song That's Amore ("When the moon hits your eye like a big pizza pie...). Amora also borrows something from Amanda, something from Maura, and makes an attractive choice no matter what its pedigree.

Berengaria was one of the medieval queens of England - married to Richard I (also known as Richard the Lionheart).

An attractive enough name, but for die-hard Star Wars fans only.
