The first proven clan chief on record however is Robert de Munro who died in 1369; his father is mentioned but not named in a number of charters.

[6] Donald Munro was granted lands for services rendered to Malcolm II of Scotland in defeating the Danes (Vikings).

[8][6] Ferindonald is a narrow strip of land running for eight miles along the northern shore of the Cromarty Firth from Dingwall to Alness.

Kelley also speculates that the "Donald le fiz Kan" granted £10 per annum by the Treasury of Scotland in 1305,[13] is the same man, with a Norman-Scots rendition of Domnall O'Cathain.

While these findings do not exclude a much earlier founder, the degree of subsequent variation in male Munros of this haplogroup suggests a common ancestor in about the 14th century.

[17] He was married to a relative of the Earl of Ross and had many charters confirmed to him under David II of Scotland including one in 1350 for the "Tower of Strathskehech" and "Estirfowlys".

[19] Robert de Munro was killed in an obscure skirmish fighting in defence of Uilleam III, Earl of Ross in 1369.

[15] His son, Hugh Munro, was also granted many charters including one in respect of the "Tower of Strathschech" and "Wesstir Fowlys" by Euphemia I, Countess of Ross in 1394.

[20][21] In 1411 a major feud broke out between Robert Stewart, Duke of Albany and Domhnall of Islay, Lord of the Isles over the Earldom of Ross.

This resulted in the Battle of Harlaw where chief Hugh Munro, 9th Baron of Foulis rose up in support of the Lord of the Isles.

[24] In 1428 a group of Munros were granted remission by King James I of Scotland for past offences when he came to Inverness to assert his authority in the Highlands.

This resulted in the Battle of Bealach nam Broig, fought north-west of Ben Wyvis, where the Munros and Dingwalls rescued the Ross hostage and exterminated their enemies but with a great loss of their own men.

In 1497, MacDonald of Lochalsh rebelled against the king, invading the lands of Ross-shire where, according to early 19th-century historian Donald Gregory, he was defeated at the Battle of Drumchatt (1497) by the Munros and Mackenzies.

[36] In 1529 a charter was signed between chief Hector Munro, 13th Baron of Foulis and Lord Fraser of Lovat to assist and defend each other.

[33] A little later in 1547, Robert Munro, 14th Baron of Foulis "with his friends and followers having gone to resist the English who invaded Scotland", was killed at the Battle of Pinkie Cleugh.

[39][40] Robert Mor Munro, 15th Baron of Foulis was a staunch supporter and faithful friend of Mary, Queen of Scots, and consequently was treated favourably by her son James VI of Scotland.

[41] Between 1569 and 1573 Andrew Munro, 5th of Milntown defended and held, for three years, Chanonry Castle, which he had received from the Regent Moray who died in 1569, against the Clan MacKenzie, at the expense of many lives on both sides.

His account of his experience during the Thirty Years' War was published as Monro, His Expedition With the Worthy Scots Regiment Called Mac-Keys.

[50] Sir George Munro, 1st of Newmore who fought in Ireland as a Covenanter later became a royalist after his uncle Robert Monro was imprisoned by Cromwell in 1648.

[53] On hearing of this rising, James Graham, 1st Marquess of Montrose, leader of royalist forces and his invading army of foreigners landed in Ross-shire, hoping for support from the clans.

Mackenzie's Earl of Seaforth title came to an end in 1716, and it was arranged that while Clan Ross held the county parliamentary seat the Munros would represent the Tain Burghs.

Allowed "their own way of fighting", each time they received the French fire Col. Sir Robert Munro ordered his men to "clap to the ground" while he himself, because of his corpulence, stood alone with the colours behind him.

[40][67][68] In June, 1745, a month after the Battle of Fontenoy, Sir Robert Munro, 6th Baronet was "rewarded" by an appointment to succeed General Ponsonby as Colonel of the English 37th Regiment of Foot.

[68] The Jacobites wished to do special honour to their opponent: they (the Macdonalds),[68] buried Robert in the grave of Sir John de Graham who died at the first Battle of Falkirk (1298).

[40][68] Robert's son, Sir Harry Munro, 7th Baronet, who served as an officer in Loudon's Highlanders, had been captured at the Battle of Prestonpans in September, 1745.

Harry set about rebuilding the castle as it is today, incorporating what he could of the original building which now appears as a mansion house built in a formal Georgian style rather than the defensive fort it once was.

From the Monro of Fyrish branch of the clan four generations occupied successively the position of (Principal) Physician of Bethlem Royal Hospital.

John U. Monro, dean of Harvard College, was a member of the tenth generation of the Lexington, Massachusetts branch of Clan Munro.

The 11th Baronet Foulis was succeeded by his eldest daughter Eva Marion Munro as chief of the clan, two sons having predeceased him.

Eva Marion Munro married Col C. H. Gascoigne, and their son Patrick took the surname 'Munro' of his maternal grandfather to become clan chief.
