Helisent

Helisent was used in the medieval days and has royal antecedents found in both France and Germany. Information on its origins is sketchy, but some say it's related to Elise or Helen or Heloise, or that it derives from a Visigothic name meaning "temple path". Variants include Elisende, Elisenda, Elysant, Elysande, Elissent and Elisent.

In modern times, it's found in the "Final Fantasy" video game and very occasionally on a real live baby.

Pronounced HEL-uh-sent.
