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, VII. SIR ALEXANDER LESLIE, EARL OF ROSS, who married Isabella, daughter of Robert Stewart, Duke of Albany, Governor of Scotland, and by her had issue an only daughter, Lady Euphemia, or Mary, who became a nun, and resigned the earldom in favour of her maternal uncle, John, Earl of Buchan. Donald, Lord of the Isles, who married her father's sister, Margaret, disputed Euphemia's right to put the earldom past her aunt, and the battle of Harlaw was fought in 1411 to decide the issue, which, as already stated, turned, so far as the possession of the great earldom was concerned, in favour of the Lord of the Isles, since known as Donald of Harlaw. From this point the history of the earldom falls properly to be dealt with and is given at length in The History of the Macdonalds and Lords of the Isles. But thus far it cannot fail to be extremely interesting to all the members of the clan Mackenzie, whether they believe in the Gillanders and O'Beolans or in the Fitzgeralds as the progenitors of the race; for in any case the clan was in its earlier annals closely allied with the O'Beolan Earls of Ross by descent and marriage.

It has been established that Gillanders and O'Beolan were the names of the ancient and original Earls of Ross, and they continued to be represented in the male line by the Old Rosses of Balnagowan down to the end of the eighteenth century, when the last heir male of that family, finding that the entail ended with himself, sold the estates to General Ross, brother of Lord Ross of Hawkhead, who, although possessing the same name, was of a different family and origin. It will, it is believed, be now admitted with equal certainty that the Rosses and the Mackenzies are descended from the same progenitor, Beolan or Gilleoin na h'Airde, the undoubted common ancestor of the old Earls of Ross, the Gillanders, and the Rosses. The various steps in the earliest portion of the genealogy connecting the Mackenzies with the common ancestor will be given with the same detail as that of the Rosses, and it will be stated with sufficient accuracy to justify the conclusions at which, in common with Dr Skene and all the best authorities on the subject, we have arrived. The genealogy of the Clan Andres or Rosses in the manuscript of 1467, is as follows:--

"Pol ic Tire, ic Eogan, ic Muiredaigh, ic Poil, ic Gilleanrias, ic Martain, ic Poil, ic Cainig, ic Cranin, ic Eogan, ic Cainic, ic Cranin, McGilleoin na h'Airde, ic Eirc, ic Loirn, ic Fearchar, Mc Cormac, ic Abertaig, ic Feradaig."
