Earl Hugh married, secondly, also by dispensation from the Pope, in 1329, Margaret, daughter of Sir David de Graham.
The Earl was killed at the battle of Halidon Hill in 1333, when he was succeeded by his eldest son, V. WILLIAM O'BEOLAN, EARL OF ROSS AND LORD OF SKYE, banished to Norway for some serious offence, but in 1336 he is found in actual possession of the earldom. He was afterwards Justiciar of Scotland, and in a charter of 1374 he is designated "frater Regis," or the King's brother, no doubt from the fact that his sister Euphemla was the wife of Robert II. He rebuilt the Abbey of Fearn, and married his cousin Isobel, daughter of Malise, Earl of Stratherne, Orkney, and Caithness, with issue -
1. William, who died before his father
2. Euphemia, who became Countess of Ross in her own right on the death of her father.
3. Johanna, who, in 1375, married Sir Alexander Fraser, Lord of Cowie and Durris, ancestor of the Frasers of Philorth and Pitsligo, now represented by Lord Saltoun. Johanna first carried the lands of Philorth to that family. She has a charter in 1370.
William died on the 9th of February, 1372, without surviving male issue, when he was succeeded by his eldest daughter,
VI. EUPHEMIA O'BEOLAN, COUNTESS OF ROSS in her own right. She married first, by dispensation, dated 1367, Sir Walter Leslie, son of Sir Andrew Leslie, who in right of his wife became Earl of Ross. They have a charter of the earldom of Ross and of the lands of Skye dated 1370, two years before Earl William's death, in their own favour and that of their heirs male and female in reversion. Her first husband predeceased her in 1382, whereupon she married, secondly, Alexander, Earl of Buchan, better known in history as "The Wolf of Badenoch." He died, without issue, in 1394. She died Abbess of Elcho in 1398, and was buried in Fortrose Cathredral. By Sir Walter Leslie she had issue -
1. Sir Alexander Leslie, who became Earl of Ross in right of his mother.
2. Margaret Leslie, who married Donald, second Lord of the Isles, who in her right, after fighting the battle of Harlaw, succeeded to the earldom of Ross, and carried it to a new family, the Macdonald Lords of the isles.
When the Countess Euphemia died, in 1398, she was succeeded by her only son,
