Melusina

A variation of mystical Melusine, a water fairy from European folklore who turned into a serpent once a week. The mythological figure is sometimes said to be the forbearer of a number of royal European lineages, including the Limburg-Luxemburg dynasty.

The name was borne by Petronilla Melusina von der Schulenburg, an illegitimate daughter of King George I of Britain.

Pronounced muh-loo-SEE-nuh.
