Patrick IV, Earl of March
Patrick IV, Earl of March( 124210 October 1308), sometimes called Patrick de Dunbar" 8th" Earl of March, was the most important magnate in the border regions of Scotland.
He was one of the Competitors for the Crown of Scotland.
Mary de Monthermer
Mary MacDuff, Countess of Fife ("née" de Monthermer; October 1297 – circa 1371) was an English noblewoman.
She was a daughter of Ralph de Monthermer, 1st Baron Monthermer and his wife Joan of Acre.
Other sources have her being born in 1298.
Donnchadh IV, Earl of Fife
Donnchadh IV, Earl of Fife
[Duncan IV] (1289–1353) was sometime Guardian of Scotland, and ruled Fife until his death.
He was the last of the native Scottish rulers of that province.
He was born in late 1289, the same year as his father Donnchadh III's murder.
He therefore came into the Mormaerdom as a baby.
He was so young that the honour of crowning John Balliol – normally the hereditary right of the Mormaer of Fife – was delegated to a knight, namely Sir John de St. John.
He also missed the crowning of Robert I, owing to his captivity in England.
Robert was forced to call upon Donnchadh's sister, Isabella, to officiate in his absence.
His initial support for Robert has been doubted, but in 1315, a year after the Battle of Bannockburn, he resigned his Mormaerdom to King Robert for a regrant.
The agreement with Robert ensured that the Mormaerdom would not be held by the king, and that the arms of Fife should always be unique from the similar royal arms.
If Donnchadh were to die childless, King Robert would grant it to someone, by default Alan of Menteith.
This was because Donnchadh's wife was in the custody of the English, and there was obviously some pressure from the men of Fife to retain their own regional ruler.
He was present at the negotiations which led to the Treaty of Edinburgh, and a signatory to the Declaration of Arbroath.
The Earl of Fife fought with the Bruce loyalists at the Battle of Dupplin Moor
where, he being made prisoner, changed sides and, with William Sinclair, Bishop of Dunkeld, a great adherent of Robert the Bruce, crowned Edward Balliol King of Scots at Scone on 24 September 1332.
The following year, on 19 July 1333, he fought with the Scottish army at the Battle of Halidon Hill, when he was again captured.
In 1306, Donnchadh married Mary de Monthermer, a granddaughter of Edward I of England.
He died with no male heirs.
He is important because he was the last male Gaelic ruler of Fife.
When he died in 1353, he was succeeded in his mormaerdom by his daughter Isabella, who married four times:
Isabella signed the Earldom of Fife over to Robert Stewart, 1st Duke of Albany in 1371.
Robert Bruce, Lord of Liddesdale
Sir Robert Bruce, Lord of Liddesdale( died 11 August 1332) was an illegitimate son of King Robert the Bruce and an unknown mother.
He was knighted and awarded the royal arms at the Battle of Bannockburn.
His father made him Lord of Liddesdale after William II de Soules was found guilty of treason at the Black Parliament of 1320.
It has been suggested that he may have been the father of Thomas Bruce, 1st Baron of Clackmannan, but there is no clear evidence for this.
Faced with Edward Balliol's invasion of Scotland, he and Donnchadh IV, Earl of Fife carried out an unsuccessful attempt on 6 August 1332 to repel the landing at Kinghorn in Fife.
He then quarrelled with the regent, Donald II, Earl of Mar.
He was killed leading a charge at the Battle of Dupplin Moor on 11 August 1332.
