Mariota, Countess of Ross
Mariota, Countess of Ross( Mairead, also called Mary and Margaret; died 1440) was the daughter of Euphemia I, Countess of Ross and her husband, the crusading war- hero Walter Leslie, Lord of Ross.
Upon the death of her brother, Alexander Leslie, Earl of Ross, she became the heir- presumptive of her niece Euphemia II, Countess of Ross although her husband Domhnall of Islay, Lord of the Isles pressed Mariota's superior claim to the earldom.
Domhnall attempted to gain control of the earldom, and sometime after 1405 but before 1411, Domhnall gained control of Dingwall Castle.
In the year after the death of the nominal king Robert III of Scotland( 1406), in August 1407, Domhnall sent emissaries to England to the heir of the throne, the captive James Stewart.
King Henry IV of England sent his own emissaries the following year to negotiate an alliance against Robert Stewart, Duke of Albany, the Guardian of Scotland who was controlling Euphemia and the earldom.
With control over the principal seat of the earldom of Ross and support of the exiled heir to the Scottish throne, in 1411 Domhnall felt strong enough to march against Albany's main northern ally, Alexander Stewart, Earl of Mar.
At the Battle of Harlaw Domhnall failed to inflict a decisive victory, and withdrew back to the western highlands.
In the aftermath, Albany was able to retake Dingwall and seize control of Easter Ross.
In 1415, Euphemia was persuaded by Albany to resign the earldom to his own second son, John Stewart, Earl of Buchan.
This action was challenged by Domhnall of Islay, who continued to claim the earldom on behalf of Mariota.
After the return of King James the latter destroyed the power of the Albany Stewarts, executing the Albany's son and successor Murdoch Stewart, Duke of Albany.
Domhnall had died in 1423, but Mariota continued to enjoy the support of his successor and her own son, Alexander.
Alexander took over her claims, and in 1437 her son was recognized as earl by the king.
She died in 1440.
She had two known children, Alexander and Mariota.

He was the son of Aonghas Óg, chief of Clan Donald( Clann Domhnaill), and claimant to the Lordship of the Isles, which had been held by his grandfather John of Islay, Earl of Ross( Eoin MacDomhnaill).
While just an infant, Domhnall Dubh was captured by Cailean I, Earl of Argyll. and imprisoned in Innischonnel Castle in Loch Awe.
He remained in captivity for most of his life.

Donald of Islay, Lord of the Isles
Donald, Lord of the Isles
(Gaelic: "Dómhnall"; died 1423), was the son and successor of John of Islay, Lord of the Isles and chief of Clan Donald.
The Lordship of the Isles was based in and around the Scottish west-coast island of Islay, but under Donald's father had come to include many of the other islands off the west coast of Scotland, as well as Morvern, Garmoran, Lochaber, Kintyre and Knapdale on the mainland.
Donald was the grandson of King Robert II of Scotland and first cousin of King Robert III; he took pride in his royal blood, even adopting the royal tressure to surround his coat of arms.
While it is customary to portray the Lords of the Isles as divorced from the mainstream of Scottish political life, and as representatives of a brand of lordship distinct from the rest of Scotland, this view obscures the fact that Donald was only one of many magnates who held large lordships with little interference from the crown in late 14th and early 15th century Scotland.
The Douglas kindred of southern Scotland and the Albany Stewarts had similar roles as Donald.
John de Moravia, 8th Earl of Sutherland

Alexander of Islay, Earl of Ross
Alexander of Islay or Alexander MacDonald (died 1449) was a medieval Scottish nobleman, who succeeded his father Domhnall of Islay as Lord of the Isles (1423–1449) and rose to the rank of Earl of Ross (1437–49).
His lively career, especially before he attained the earldom of Ross, led Hugh MacDonald, the 17th century author of "History of the MacDonalds", to commemorate him as "a man born to much trouble all his lifetime".
Alexander allied himself with King James I of Scotland against the power of the
Albany Stewarts in 1425 but, once the Albany Stewarts were out of the way, Alexander quickly found himself at odds with the new king.
War with King James would initially prove Alexander's undoing, and would see the King's power in Scotland greatly increased, but at the Battle of Inverlochy Alexander's army prevailed against the forces of the King.
Alexander died in 1449, having greatly extended his family's landed wealth and power.
He was buried, not in the Isles of his ancestors, but at Fortrose Cathedral in his mainland Earldom of Ross.
Euphemia II, Countess of Ross
Euphemia II, Countess of Ross( also Euphemia Leslie) was the daughter of Alexander Leslie, Earl of Ross and his wife Isabella Stewart, daughter of Robert Stewart, 1st Duke of Albany.
She was the only child and heir of Earl Alexander, and succeeded to the earldom" de jure" upon his death in 1402.
She became a ward of her grandfather Albany, and never seems to have exercised much power in the province of Ross.
There was a failed attempt to marry her to Thomas Dunbar, the son of Thomas Dunbar, Earl of Moray.
Governor Albany persuaded her to resign the earldom to his own second son, John Stewart, Earl of Buchan.
This action was challenged by Domhnall of Islay, Lord of the Isles, who claimed the earldom on behalf of his wife Mariota and who became an enemy of the Albany Stewarts.
Euphemia thereafter disappears from the record, retiring to the nunnery of North Berwick.
Some of the histories report that she was deformed, seemingly a hunchback.
