The Public Register of All Arms and Bearings in Scotland, established in 1672, is an official register of Scottish coats of arms maintained by the Lyon Clerk and Keeper of the Records. As a public register, it can be seen by anyone on application, and on payment of a statutory fee.
The Register was established by Act of the Scottish Parliament in 1672. It is held at the Court of the Lord Lyon, and contains every grant of arms by Lord Lyon King of Arms since that date, as well as older coats of arms that the owners have chosen to register. Bearings that are not matriculated in the Register may not be used in Scotland, unless it can be proved that they were in use before 1672.
The first volume of the Register (now divided into two parts for ease of handling and conservation reasons) continued in use from 1672 until 1804, and contains 2,702 entries.  It begins with the arms of the Lyon Office, followed by the personal achievement of Sir Charles Erskine, Bt, who was Lord Lyon at the time. Most of the arms in this volume are given in blazon only: relatively few are painted. 
From the beginning of the second volume in 1804 the arms are consistently painted.  The Register now consists of over eighty volumes of parchment, and is illustrated by a succession of the most prominent heraldic artists working in Scotland.
In 1893, Sir James Balfour Paul, Lord Lyon King of Arms, published the contents of the first twelve volumes of the Register, to that date, in the form of an ordinary (i.e. with the entries in blazon, rearranged by design; and with a name index): the work contained roughly 5,200 entries. Ten years later, by which time the Register had reached its sixteenth volume, he published an updated second edition including all arms registered to the end of 1901: this edition contained 5,532 entries. By 1973 the Register had reached its 57th volume, and in 1977 Lyon Office published a second volume of the Ordinary: this covered all arms registered from 1902 to the end of 1973, and contained a further 6,040 entries. This volume was edited by David Reid of Robertland, Carrick Pursuivant (who died in December 1973, while the work was in progress), and Vivien Wilson.
The three published volumes are therefore:
The Register down to 1913 has been digitised, and is available on the ScotlandsPeople Website (maintained by the National Records of Scotland). Searching the index is free, but there is a fee to view the page images.
Diaper is any of a wide range of decorative patterns used in a variety of works of art, such as stained glass, heraldic shields, architecture, and silverwork. Its chief use is in the enlivening of plain surfaces.
The Right Honourable the Lord Lyon King of Arms, the head of Lyon Court, is the most junior of the Great Officers of State in Scotland and is the Scottish official with responsibility for regulating heraldry in that country, issuing new grants of arms, and serving as the judge of the Court of the Lord Lyon, the oldest heraldic court in the world that is still in daily operation.
Ordinaries in heraldry are sometimes embellished with stripes of colour alongside them, have lumps added to them, shown with their edges arciform instead of straight, have their peaks and tops chopped off, pushed up and down out of the usual positions, or even broken apart.
Earl of Airlie is a title of the peerage in Scotland created on 2 April 1639 for James Ogilvy, 7th Lord Ogilvy of Airlie, along with the title “Lord Ogilvy of Alith and Lintrathen.” The title “Lord Ogilvy of Airlie” was then created on 28 April 1491.
In heraldry, an ordinary is a simple geometrical figure, bounded by straight lines and running from side to side or top to bottom of the shield. There are also some geometric charges known as subordinaries, which have been given lesser status by some heraldic writers, though most have been in use as long as the traditional ordinaries. Diminutives of ordinaries and some subordinaries are charges of the same shape, though thinner. Most of the ordinaries are theoretically said to occupy one-third of the shield; but this is rarely observed in practice, except when the ordinary is the only charge.
The lozenge in heraldry is a diamond-shaped charge, usually somewhat narrower than it is tall. It is to be distinguished in modern heraldry from the fusil, which is like the lozenge but narrower, though the distinction has not always been as fine and is not always observed even today. A mascle is a voided lozenge—that is, a lozenge with a lozenge-shaped hole in the middle—and the rarer rustre is a lozenge containing a circular hole in the centre. A field covered in a pattern of lozenges is described as lozengy; similar fields of mascles are masculy, and fusils, fusily. In civic heraldry, a lozenge sable is often used in coal-mining communities to represent a lump of coal.
An armigerous clan is a Scottish clan, family or name which is registered with the Court of the Lord Lyon and once had a chief who bore undifferenced arms, but does not have a chief currently recognised as such by Lyon Court. Before 1745 all chiefs had arms; however, not all of these are recorded in the Public Register of All Arms and Bearings in Scotland, which was established in 1672.
The law of heraldic arms governs the "bearing of arms", that is, the possession, use or display of arms, also called coats of arms, coat armour or armorial bearings. Although it is believed that the original function of coats of arms was to enable knights to identify each other on the battlefield, they soon acquired wider, more decorative uses. They are still widely used today by countries, public and private institutions and by individuals. The earliest writer on the law of arms was Bartolus de Saxoferrato. The officials who administer these matters are called pursuivants, heralds, or kings of arms. The law of arms is part of the law in countries which regulate heraldry, although not part of common law in England and in countries whose laws derive from English law.
Heraldry in Scotland, while broadly similar to that practised in England and elsewhere in western Europe, has its own distinctive features. Its heraldic executive is separate from that of the rest of the United Kingdom.
Lyon Clerk and Keeper of the Records is a legal and heraldic office in Scotland. The holder of this office is appointed by the Crown, and like the Lord Lyon King of Arms receives an annual salary. Lyon Clerk's duties include heraldic research, the preparation of papers, lectures and conducting and assisting with the preliminary business of application for a grant or matriculation of armorial bearings. This includes scrutiny of documents supporting the application. As Keeper of the Records the duties include maintaining the records of the Court of the Lord Lyon, overseeing the preparation of documents, allowing inspection of the Public Register of All Arms and Bearings in Scotland and other records, and issuing certified extracts when required. Until 1867 there was a Lyon Clerk Depute, and in 1986 Elizabeth Ann Roads became the first woman appointed to the office of Lyon Clerk and Keeper of the Records.
Sir James Balfour Paul was the Lord Lyon King of Arms, the officer responsible for heraldry in Scotland, from 1890 until the end of 1926.
In heraldry, a bordure is a band of contrasting tincture forming a border around the edge of a shield, traditionally one-sixth as wide as the shield itself. It is sometimes reckoned as an ordinary and sometimes as a subordinary.
Clan Kincaid is a Scottish clan.
Sir Robert Lauder of Beilmouth, Knt., was an armiger, lawyer and Clerk of Exchequer in Scotland. In 1683 he was made a Justice of the Peace for Haddingtonshire. As Robert Lauder of Belhaven he was in the old Scottish parliament for Haddington in 1685, and, as Sir Robert Lauder of Beilmouth, in 1704. He was also Commissioner of Supply for Haddington in 1689 and 1690.
The arms of the city of Edinburgh, more properly the arms of the city council, were registered with the Lord Lyon King of Arms in 1732, having been used unofficially for several centuries previously. The central symbol is a heraldic castle, representing Edinburgh Castle.
The Scots Peerage is a nine-volume book series of the Scottish nobility compiled and edited by Sir James Balfour Paul, published in Edinburgh from 1904 to 1914. The full title is The Scots Peerage: Founded on Wood's Edition of Sir Robert Douglas's Peerage of Scotland, containing an Historical and Genealogical Account of the Nobility of that Kingdom.
In heraldry, a pile is a charge usually counted as one of the ordinaries. It consists of a wedge emerging from the upper edge of the shield and converging to a point near the base. If it touches the base, it is blazoned throughout.
The Court of the Lord Lyon is a standing court of law 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.
Sir Alexander Erskine of Cambo, 2nd Baronet of Cambo, Fife was a Scottish baronet and Lord Lyon, King of Arms.
An ordinary of arms is a roll or register of coats of arms arranged systematically by design, with coats featuring the same principal elements grouped together. The purpose of an ordinary is to facilitate the identification of the bearer of a coat of arms from visual evidence alone.
