Ilse

The German girl’s name Ilse means “oath of God.” A different and more recognizable version of this name is Elsa. From Elsa of Arendelle in Frozen to Spanish model and actress Elsa Pataky, this name has definitely grown in popularity in recent years. If you have always liked the sound of the name Elsa but maybe are not sold on its popularized spelling, the name Ilse would be a charming alternative.
