(Saint) Margaret of Wessex, great-granddaughter of Ethelred Unraed, granddaughter of Edmund Ironside and great-niece of (St.) Edward the Confessor, died just three days after her husband, Malcolm III was killed at Alnwick in 1093. She, as eventual heiress to the House of Wessex, was the ancestor of every subsequent Scottish monarch except Donald Bain, Malcolm’s brother.

As this Dundee Courier article explains, most of her remains were transferred to the Estorial Monastery in Spain. Her head, sent to the (Douai) Scots College, but was lost during the Revolution, as so many remains and statues were damaged at the same time. Fortunately, one shoulder bone has been returned to Dunfermline, the town of her original shrine, such that it or a 3D replica can be analysed.
