I've come across two characters from German folklore: King Ilsing and his daughter PrincessIlse. The Ilse river is supposedly named for her. Does anyone know what Ilse and Ilsing mean? I suppose Ilse could be a nn for Elisabeth but the fact that her name comes from German folklore makes me think there's another answer.
