James of Mar, 30th Earl of Mar
James Clifton of Mar, 30th Earl of Mar( 22 November 1914 – 21 April 1975) was a Scottish peer.
He was born James Clifton Lane, and was officially recognized in the style" of Mar" by warrant of the Lord Lyon in 1959 on being recognised as the heir presumptive of Lionel Erskine- Young, 29th Earl of Mar, his first cousin once removed( both he and the 29th Earl were descended from a sister of John Goodeve- Erskine, 27th Earl of Mar), and from then on was known as The Master of Mar, until he succeeded as 30th Earl in 1965.
His only son, David, Master of Mar, Lord Garioch, died in 1967, and when Lord Mar died in 1975 he was succeeded by his elder daughter, Margaret of Mar, Mistress of Mar.
Thomas, Earl of Mar
Thomas, Earl of Mar,( c. 1330- 1377) was a 14th- century Earl of Mar, an earldom located in the County of Aberdeen, Scotland.
He is sometimes styled Mormaer of Mar since" mormaer" was the Scottish equivalent of the English word earl.
Because the identification and numbering of the ancient earls of Mar is debatable, Thomas is variously numbered the ninth, tenth, or thirteenth.
of the ancient earls.
He was a son of Domhnall II of Mar, who fell at the Battle of Dupplin Moor in 1332.
Domhnall I, Earl of Mar
Domhnall I Earl of Mar-
Domhnall mac Uilleim( Anglicized: Donald, William's son)- was the seventh known Mormaer of Mar, or Earl of Mar ruling from the death of his father, Uilleam of Mar, in 1276 until his own death somewhere between 1297 and 1302.
Excluding Gille Christ he is counted as sixth Mormaer or Earl of Mar.
In 1284 he joined with other Scottish noblemen who acknowledged Margaret of Norway as the heir to King Alexander.
Domhnall was later a strong supporter of the Bruce cause during the crisis of the late 13th century.
He was at Norham in 1292, probably in the camp of Robert de Brus, then Earl of Carrick.
He married to Helen( sometimes called Ellen), possibly the natural daughter of Llywelyn the Great of Wales, who herself had previously been married to Mormaer Maol Choluim II, Earl of Fife.
By Helen, he had three sons, including his successor Gartnait, and two daughters.
His daughter Isabella of Mar was the first wife of Robert I of Scotland and mother of Marjorie Bruce who married Walter, 6th High Steward, the parents of Robert II and the Royal Stewart Kings of Scotland.
The last record of a living Domhnall comes from 1297, and the earliest record of his son Gartnait as Mormaer is from 1305, creating the range of Domhnall's possible year of death to somewhere in between these two points.
However, a document dating to 1302, containing terms of reconciliation between Edward I and Robert, stipulates that Robert should act as warden of Gartnait, implying that Domhnall had just died.
Susan of Mar, Mistress of Mar
Susan Helen of Mar, Mistress of Mar( born 31 May 1963) is the only child and heir presumptive of Margaret of Mar, 31st Countess of Mar.

Kenneth ’s mother is unknown.
Kenneth succeeded to the earldom on the death of his brother William de Moravia, 3rd Earl of Sutherland, in about December 1330.
Kenneth is thought to have married Mary( or Marjorie) of Mar, the widow of John of Strathbogie, Earl of Atholl who was executed by the English in London on 7 November 1306.
She was the daughter of Domhnall I, Earl of Mar and Helen verch Llewellyn, a daughter of Llewelyn the Great.

Domhnall II, Earl of Mar
Domhnall II, Earl of Mar (129311 August 1332) was briefly Regent of Scotland during the minority of David II, King of Scotland.
Domhnall's father was Gartnait, Earl of Mar.
His mother's identity is uncertain, although she seems to have been an elder daughter of Robert Bruce, Earl of Carrick.
It appears likely that he fought on the side of Edward II of England at the Battle of Boroughbridge in March 1322, as it is recorded that afterwards the Earl of Mar took Bartholomew de Badlesmere, who was one of Edward's captured opponents, to Canterbury.
In 1332 the regent of Scotland, Thomas Randolph, 1st Earl of Moray, died.
On 2 August Domhnall was elected as the new regent at a meeting of the Scottish nobles at Perth.
Following the invasion of Edward Balliol, with the support of Edward III of England, Mar led the Scots loyalists to confront them.
He was defeated and killed at the Battle of Dupplin Moor, only nine days after his election as regent.
Through his marriage to Isabella Stewart, daughter of Sir Alexander Stewart of Bonkyll and
Jean Fitz James, they had a son, Thomas of Mar, and a single daughter, Margaret of Mar, who succeeded her brother and became, in her turn, Countess of Mar.
