Hildegarde’s direct predecessor was Hildur, chief among the Valkyries.
In England there was a Deiran princess Hildur who became the holy abbess of Whitby, succeeding St. Begga.

Hildegarde was first bestowed upon an abbess in the Palatinate, who was noted for her sanctity and who died as late as 1004. In honor of the holy woman, Hildegard is still very popular and in common usage among German ladies.
In Denmark, the same name has been most identical, Hilduara, meaning battle prudence.
Amber is Hildegarde’s talismanic stone. It is said to protect her from danger and disease and to strengthen the health of mind and body. It is particularly lucky for singers, preserving and clarifying the voice, according to old superstition.
