John de Innes
John de Innes( c. 1370 – 1414) was medieval Scottish churchman.
Born probably in Moray, he went to France in his youth, receiving a bachelorate in civil law from the University of Paris by 1396 and in canon law by 1407.
His education was partly paid for by the prebend of Duffus and a grant from Alexander Bur, Bishop of Moray, taken by Bur from the judicial profits of his diocese.
During Innes' study period, he was also pursuing an ecclesiastical career, being Archdeacon of Caithness from 1396 until 1398, and Dean of Ross, from some point between 1396 and 1398 until 1407.
He gave up the latter position in that year, having been elected as Bishop of Moray sometime in late 1406, and receiving consecration from Pope Benedict XIII in either Italy or southern France in the following January.
Innes was bishop for over seven years, and died at Elgin on 2 August 1414.
Innes has been traditionally credited with supervising much of the rebuilding to Elgin Cathedral.
The historian David Ditchburn believes Innes was an ally, and possibly even a client, of Alexander Stewart, Earl of Mar, and perhaps his father Alexander Stewart, Earl of Buchan, the latter of whom was the warlord responsible for burning down Elgin Cathedral during the episcopate of Alexander Bur.
Alexander Stewart, Earl of Buchan
Alexander Stewart, Earl of Buchan, Alasdair Mór mac an Rígh, and called the Wolf of Badenoch (1343 – 20 June 1405), was the third surviving son of King Robert II of Scotland and youngest by his first wife, Elizabeth Mure of Rowallan.
He was the first Earl of Buchan since John Comyn, from 1382 until his death.
Alexander married the widowed Euphemia I, Countess of Ross, but they had no children.
He did have a large family by his longtime mistress, Mairead inghean Eachainn.
Alexander was Justiciar of Scotia for a time, but not an effective one.
He held large territories in the north of Scotland before eventually losing a large part of them.
Alexander is remembered for his destruction of the royal burgh of Elgin and its cathedral.
His nickname was earned due to his notorious cruelty and rapacity, but there is no proof that it was used during his lifetime.
Alice Comyn, Countess of Buchan
Alice Comyn, Countess of Buchan, Lady Beaumont( 1289 – 3 July 1349) was a Scottish noblewoman, a member of the powerful Comyn family which supported the Balliols, claimants to the disputed Scottish throne against their rivals, the Bruces.
She was the niece of John Comyn, Earl of Buchan, to whom she was also heiress, and after his death the Earldom of Buchan was successfully claimed by her husband Henry de Beaumont, Earl of Buchan, by right of his wife.
His long struggle to claim her Earldom of Buchan was one of the causes of the Second War of Scottish Independence.
Alice was the maternal grandmother of Blanche of Lancaster, and thus great- grandmother of King Henry IV of England.
Elizabeth Mure
Elizabeth Mure (died before May 1355) was mistress and then wife of Robert, High Steward of Scotland, and Guardian of Scotland (
1338–1341 and from October 1346), who later became King Robert II of Scotland.
Elizabeth Mure was said to be born at Rowallan Castle.
Her parents were Sir Adam Mure of Rowallan, Ayrshire and Janet Mure of Pokellie.
She initially became the Steward's mistress.
He married her in 1336 but the marriage was criticised as uncanonical, so he remarried her in 1349 following a papal dispensation dated at Avignon 22 November 1347.
She died before her husband inherited the crown at the age of 55 in 1371, and he later remarried (Papal Dispensation dated 2 May 1355).
On 27 March 1371, "The Lord John (who later took the title of King Robert III, changing his name because of what he saw as John de Baliol's unpatriotic desecration of the name John), Earl of Carrick and Steward of Scotland, first-born son of King Robert II" was declared heir to the Crown by Parliament in Scone Abbey.
They had at least ten children, with some accounts saying as many as thirteen.
Doubts about the validity of her marriage led to family disputes over her children's right to the crown.
James Erskine, 6th Earl of Buchan
James Erskine, 6th Earl of Buchan( died 1640), was the eldest son of John Erskine, Earl of Mar, by his second wife, Marie Stewart, daughter of Esme Stewart, Duke of Lennox.
He married Mary Douglas, 6th Countess of Buchan, daughter and heiress of James Douglas, 5th Earl of Buchan, and assumed the title of Earl of Buchan.
This title was confirmed by a royal charter, dated 22 March 1617, the countess resigning her rights in his favour, and he was allowed the possession and exercise of all honours, dignities, and precedence of former earls of Buchan.
A decree of the court of sessions, 25 July 1628, restored to Buchan and his wife the precedency over the earls of Eglinton, Montrose, Cassilis, Caithness, and Glencairn, which had been claimed by them, and granted by a former decree in 1606.
On the accession of Charles I, Buchan became one of the lords of the bedchamber.
He lived chiefly in London, where he died in 1640.
He was buried at Auchterhouse, Forfarshire.
His wife died before him in 1628.
They left six children, two sons, James, who succeeded to the title, and John, and four daughters.
