In heraldry, cadency is any systematic way to distinguish arms displayed by descendants of the holder of a coat of arms when those family members have not been granted arms in their own right. Cadency is necessary in heraldic systems in which a given design may be owned by only one person at any time, generally the head of the senior line of a particular family.
As an armiger's arms may be used 'by courtesy', either by children or spouses, while they are still living, some form of differencing may be required so as not to confuse them with the original undifferenced or "plain coat" arms. Historically, arms were only heritable by sons, and therefore cadency marks had no relevance to daughters; in the modern era, Canadian and Irish heraldry include daughters in cadency.
These differences are formed by adding to the arms small and inconspicuous marks called brisures, similar to charges but smaller. They are typically placed on the fess point (the centre of the field), or in chief (the upper part of the field) in the case of the label.Encyclopædia Britannica, 9th edition (1884), vol. 11, p. 704 Brisures are generally exempt from the rule of tincture. One of the best examples of usage from the medieval period is shown on the seven Beauchamp cadets in the stained-glass windows of St Mary's Church, Warwick.
Background
Historically, it was recognised that there was a need to difference the arms of the head of the family from those of cadets. This need was recognised in Europe during the 14th century; various means to accomplish this were used.
In the modern era, differencing arms is generally rarely done in continental Europe. It is only in Scotland where the need to difference cadets is enforced.
Ways of differencing
In heraldry's early period, uniqueness of arms was obtained by a wide variety of ways, including: changing tincture adding a label or bordure adding, removing, or replacing an ordinary. varying the lines of partition of an ordinary the use of brisures or marks of difference
See Armorial of Capetians and Armorial of Plantagenet for an illustration of the variety.
Systems derived from English and Scottish usage Systematic cadency schemes later developed in England and Scotland, but while in England they are voluntary (and not always observed), in Scotland they are enforced through the statutorily required process of matriculation in the Public Register.
England
The English system of cadency allows nuclear family members to personally use the arms of the head of that family 'by courtesy'. This involves the addition of a brisure, or mark of difference to the original coat of arms. The brisure identifies the bearer's family relationship to the actual bearer of the arms. Although there is some debate over how strictly the system should be followed, the accepted system is shown below: First sonSecond sonThird sonFourth sonFifth sonSixth sonSeventh sonEighth sonNinth sonfamily member label of three points crescent mullet martlet annulet fleur-de-lys rose cross moline double quatrefoil
Daughters have no special brisures, and normally use their father's arms on a lozenge, which includes any marks of cadency their father may use. This is because English heraldry has no requirement that women's arms be unique. Upon marriage, they impale their father's arms to the sinister with those of their husband to the dexter. However, if the woman happens to be a heraldic heiress, her father's arms are borne on an inescutcheon on her husband's arms.
In England, arms are generally the property of their owner from birth, subject to the use of the appropriate mark of cadency. Therefore, it is not necessary to wait for the death of the previous generation before arms are inherited.
The eldest son of an eldest son uses a label of five points. Other grandchildren combine the brisure of their father with the relevant brisure of their own. This could lead to confusion, as both an uncle and nephew could have the same cadency mark. In a short number of generations, the accumulation of cadency marks—to show, for example, the fifth son of a third son of a second son—could lead to added complexity. In practice, cadency marks are not much used in England, and even when they are, it is rare to see more than one or two on a coat of arms.
At times, arms with a cadency mark may be used on a hereditary basis. For instance, the arms of the Earls Russell are those of the Duke of Bedford differenced by a mullet, as the 1st Earl was the third son of the 6th Duke.
Although most heraldic texts follow on the English system of cadency set out above, most heraldic examples (whether on old bookplates, church monuments, silver and the like) ignore cadency marks altogether. Oswald Barron noted:
Nor have cadency marks usually been insisted upon by the College of Arms, the heraldic authority for England, Wales, and Northern Ireland. For example, a statement on their website refers to the optional nature of cadency marks:
In correspondence published in the Heraldry Society's newsletter, Garter King of Arms Peter Gwynn-Jones firmly rejected a suggestion that cadency marks should be strictly enforced. He said:
In a second letter published at the same time, he wrote:
Adopted children Clarenceux King of Arms John Brooke-Little wrote that "adopted children may be granted the arms of their adoptive father, but a Royal License must be sought, and the arms, when granted, are differences by the addition of two links of a chain interlaced, either fesswise or palewise..."
Scotland The system is very different in Scotland, where every male user of a coat of arms may only use arms recorded, or "matriculated", in the Public Register with a personal variation, appropriate to that person's position in their family, approved by the heraldic authority for Scotland, the Lord Lyon. This means that in Scotland no two men can ever simultaneously bear the same arms, even by accident, if they have submitted their position to the Scottish heraldic authorities (which not all do in practice, in Scotland as in England); if they have not done so, the matter falls under statute law and may result in proceedings in the Lyon Court, which is part of the Scots criminal justice system. To this extent, the law of arms is stricter in Scotland than in England where the only legal action possible is a civil action in the Court of Chivalry, which sits extremely rarely and is not an integrated part of the English justice system.
Scotland, like England, uses the label of three points for the eldest son (or female heir presumptive) and a label of five points for the eldest son of the eldest son, and allows the label to be removed as the bearer of the plain coat dies and the eldest son succeeds.
For cadets other than immediate heirs, Scottish cadency uses a complex and versatile system, applying different kinds of changes in each generation. First, a bordure is added in a different tincture for each brother. In subsequent generations the bordure may be divided in two tinctures; the edge of the bordure, or of an ordinary in the base coat, may be changed from straight to indented, engrailed or invected; charges may be added. These variations allow the family tree to be expressed clearly and unambiguously. The system outlined here is a very rough version that gives a flavour of the real thing.
In the Scots heraldic system (which has little to do with the clan system), only one bearer of any given surname may bear plain arms. Other armigerous persons with the same surname usually have arms derived from the same plain coat; though if actual kinship cannot be established, they must be differenced in a way other than the cadency system mentioned above.
Canada Canadian cadency generally follows the English system. However, since in Canadian heraldry a coat of arms must be unique regardless of the bearer's sex, Canada has developed a series of brisures for daughters unique to Canada:Heraldry proficiency program – Canadian Heraldic Information (5 April 2007) Heraldry.ca. Accessed 28 August 2008.
for the first daughter, a heart; for the second daughter, an ermine spot; for the third daughter, a snowflake; for the fourth daughter, a fir twig; for the fifth daughter, a chess rook for the sixth daughter, an escallop (scallop shell); for the seventh daughter, a harp; for the eighth daughter, a buckle; for the ninth daughter, a clarion.
The actual practice in Canada is far from the rigidity suggested by the list of differences above – and is best seen in action in the Canadian Public Register – see for example the coats of various Armstrongs, Ravignats and Bradfords.
South Africa
Personal arms registered at the Bureau of Heraldry may be differenced upon matriculation (which is voluntary). Current policy is that younger children's arms must be differenced if they are matriculated. Methods used include the English and Scottish systems, the substitution of different charges, the changing of lines, and the changing of tinctures and or adding a border to the shield.
Ireland
The brisures used in the arms granted by the Chief Herald of the Republic of Ireland are identical to the brisures used by the system used in England, Wales and Northern Ireland, but unlike the English system, which only uses these brisures for the sons of an armiger in order of birth, the Irish system applies them to all the children of the armiger, irrespective of sex, and, as illegitimacy has no place in Irish heraldry, these marks are assigned to (recognised) children born outside of marriage as well as inside.
British royal family
There are no actual "rules" for members of the royal family, because their arms are theoretically decided ad hoc by the monarch. In practice, however, a number of traditions are practically invariably followed. At birth, members of the royal family have no arms. At some point during their lives, generally at the age of eighteen, they may be granted arms of their own. These will always be the "arms of dominion" of the monarch with a label argent for difference; the label may have three or five points. Since this is in theory a new grant, the label is applied not only to the shield but also to the crest and the supporters to ensure uniqueness. Though de facto in English heraldry the crest is uncharged (although it is supposed to be in theory), as it would accumulate more and more cadency marks with each generation, the marks eventually becoming indistinguishable, the crests of the royal family are always shown as charged.
Each Prince of Wales uses a plain white label and (since 1911) an inescutcheon of the ancient arms of the Principality of Wales. Traditionally, the other members of the family have used a stock series of symbols (cross of Saint George, heart, anchor, fleur-de-lys, etc.) on the points of the label to ensure that their arms differ. The label of the Duke of Sussex has three scallop shells taken from the arms of his mother, Diana, Princess of Wales;Arms of Princes William and Harry, showing differencing this is sometimes called an innovation but in fact the use of maternal charges for difference is a very old practice, illustrated in the "border of France" (azure semé-de-lys or) borne by John of Eltham, Earl of Cornwall (1316–36), younger son of Edward II of England and Isabella of France.
It is often said that labels argent are a peculiarly royal symbol, and that eldest sons outside the royal family should use labels of a different colour, usually gules.
Continental usages
France
During the Middle Ages, marks of cadency were used extensively by armigers in France. By the eighteenth century, such marks were no longer used by the members of armigerous families, but were still used extensively by the members of the French royal family.
