Lilliet

This delicate and pretty member of the prolific Lily family is best known as the name of the heroine of Alexander Chee's novel Queen of the Night, Lilliet Berne. A combination of Lillian and Juliet, Lilliet and its near-twin Liliet were given to no baby girls in the US in recent years, but do have some history of use. If you can't decide between Lily and Juliet, this is obviously the name for you.

Pronounced LIL-ee-et.
