Lord Lyon King of Arms in the context of "Courts of Scotland"

The Scottish Noblesse means nobility in Scotland, including both those with peerage titles as well as those without. The concept was prominently advocated for by Sir Thomas Innes of Learney during his tenure as Carrick Pursuivant of Arms and later Lord Lyon King of Arms.

The concept of noblesse as opposed to "nobility" is old: in 1901 a Canadian heraldist Edward Marion Chadwick discussed the difference between the two in France: "pairie" is similar to English peerage, while noblesse consists of gentlemen commoners. "The King ... was the fountain of hereditary title, but not the fountain of noblesse", and noblesse can be obtained without any royal act.

Clan Campbell of Cawdor is a highland Scottish clan and a branch of the larger Clan Campbell. While the clan is recognised by the Standing Council of Scottish Chiefs, the clan does not have a clan chief recognised by the Standing Council of Scottish Chiefs. Also, because the clan does not have a clan chief recognised by the Lord Lyon King of Arms it is considered an armigerous clan. The head of the Clan Campbell of Cawdor is the Earl Cawdor, since 1993 Colin Campbell.

Laird (/ˈlɛərd/) is a Scottish word for minor lord (or landlord) and is a designation that applies to an owner of a large, long-established Scottish estate. In the traditional Scottish order of precedence, a laird ranked below a baron and above a gentleman. This rank was held only by those holding official recognition in a territorial designation by the Lord Lyon King of Arms. They are usually styled [name] [surname] of [lairdship]. However, since "laird" is a courtesy title, it has no formal status in law.

Historically, the term bonnet laird was applied to rural, petty landowners, as they wore a bonnet like the non-landowning classes. Bonnet lairds filled a position in society below lairds and above husbandmen (farmers), similar to the yeomen of England.

Clan Donald, also known as Clan MacDonald (sometime abbreviated to McDonald) (Scottish Gaelic: Clann Dòmhnaill; Mac Dòmhnaill [ˈkʰl̪ˠãũn̪ˠ ˈt̪õː.ɪʎ]), is a Highland Scottish clan and one of the largest Scottish clans. Historically the chiefs of the Clan Donald held the title of Lord of the Isles until 1493 and two of those chiefs also held the title of Earl of Ross until 1476.

The Lord Lyon King of Arms, the Scottish official with responsibility for regulating heraldry in that country, issuing new grants of coats of arms, and serving as the judge of the Court of the Lord Lyon, recognises under Scottish law the High Chief of Clan Donald. There are also numerous branches to the Clan Donald and several of these have chiefs recognised by the Lord Lyon King of Arms; these are: Clan Macdonald of Sleat, Clan Macdonald of Clanranald, Clan MacDonald of Keppoch, Clan MacDonald of Glencoe, Clan MacDonell of Glengarry, and Clan MacAlister.

Clan MacDougall is a Highland Scottish clan, historically based in and around Argyll. The Lord Lyon King of Arms, the Scottish official with responsibility for regulating heraldry in Scotland, issuing new grants of coats of arms, and serving as the judge of the Court of the Lord Lyon, recognizes under Scottish law the Chief of Clan MacDougall. The MacDougall chiefs share a common ancestry with the chiefs of Clan Donald in descent from Somerled of the 12th century (and thus further of the Viking-born Norse-Gael dynasty of House of Ivar). In the 13th century the Clan MacDougall whose chiefs were the original Lords of Argyll and later Lords of Lorne was the most powerful clan in the Western Highlands. During the Wars of Scottish Independence the MacDougalls sided with the Clan Comyn whose chiefs rivaled Robert the Bruce for the Scottish Crown and this resulted in clan battles between the MacDougalls and Bruce. This marked the MacDougall's fall from power and led to the rise of their relatives, the Clan Donald, who had supported Bruce and also the rise to power of the Clan Campbell who were then the habitual enemies of the MacDougalls and later of Clan Donald.

The MacDougalls supported the House of Stuart during the Scottish Civil War of the 17th century and during the Jacobite risings of the 18th century.

The Book of Ballymote (Irish: Leabhar Bhaile an Mhóta, RIA MS 23 P 12, 275 foll.) was written in 1390 or 1391 in or near the town of Ballymote, now in County Sligo, but then in the tuath of Corann.

According to David Sellar who was the Lord Lyon King of Arms in Scotland, the Book of Ballymote was written from between 1384 and 1405. According to Robert Anthony Welch, it was compiled in the late 14th century.

Clan Stewart (Gaelic: Stiùbhart) is a Scottish Highland and Lowland clan. The clan is recognised by Court of the Lord Lyon; however, it does not have a clan chief recognised by the Lord Lyon King of Arms. Because the clan has no chief it can be considered an armigerous clan; however, the Earls of Galloway are now considered to be the principal branch of this clan, and the crest and motto of The Earls of Galloway's arms are used in the Clan Stewart crest badge. The Court of the Lord Lyon recognises two other Stewart/Stuart clans, Clan Stuart of Bute and Clan Stewart of Appin. Stuart of Bute is the only one of the three clans at present which has a recognised chief.

The Court of the Lord Lyon, or Lyon Court, is a standing court of law, based in New Register House in Edinburgh, which regulates heraldry in Scotland. The Lyon Court maintains the register of grants of arms, known as the Public Register of All Arms and Bearings in Scotland, as well as records of genealogies.

The Lyon Court is a public body, and the fees for grants of arms are paid to His Majesty's Treasury. It is headed by the Right Honourable the Lord Lyon King of Arms, who must be legally qualified, as he has criminal jurisdiction in heraldic matters, and the court is fully integrated into the Scottish legal system, including having a dedicated prosecutor, known in Scotland as a procurator fiscal.
