Isabel Douglas, Countess of Mar

1295 – d. 17 October 1346 at the Battle of Neville's Cross, Durham, England),[6] in turn son of Sir Malcolm Drummond, 9th Thane of Lennox (b. after 1270, d. 1325), who fought in the Battle of Dunbar on 27 April 1296, where he was captured by the English, and in 1301 was again captured by the English, and wife ... de Graham, daughter of Sir Patrick de Graham, Lord of Kincardine, and wife.

[7] While the couple resided at the chief seat to the Earldom of Mar, Kildrummy Castle, Sir Malcolm was frequently away on royal business, being one of King Robert's close advisors.

[8] Because the king was by this time sick and infirm and real power was in the hands of his younger brother the Duke of Albany, Isabel was now completely isolated and was now easy prey for her husband's murderer.

Under normal circumstances this incident possibly would not have been allowed to stand, but Isabel had the misfortune that these events took place during the regency of the Duke of Albany, who was in fact the uncle of this Alexander Stewart.

Because his relation to the Royal Family and friendship with his uncle saved him from any actual punishment, Isabel was forced to marry the man who murdered her husband and live the last four years of her life as a captive.
