Ysanne

This ancient-looking name is actually a 20th century invention, on the model of Suzanne, Marianne, Yvonne and other similar names. It is the name of a seer in Guy Gavriel Kay’s Fionavar Tapestry trilogy, and notable real-life bearers include musician and food writer Ysanne Spevack, and English actress Ysanne Churchman.

Pronounced ee-SAN.
