Supporters signify some definite honour which cannot ordinarily survive illegitimacy.
The bordure wavy is placed round the pronominal arms only, and no right to any quarterings the family may have enjoyed previously is conferred, except such right to a quarterly coat as might ensue through the assumption of a double name. Quartering is held to signify representation which cannot be given by a Royal Licence, but a quartering of augmentation or a duplicate coat for the pronominal name which had been so regularly used with the alternative coat as to constitute the two something in the nature of a compound coat, would be exemplified "all within a bordure wavy." Each illegitimate coat stands on its own basis, and there is a well-known instance in which a marriage was subsequently found to be illegal, or to have never taken place, after which, I believe, some number of brothers and sisters obtained Royal Licences and exemplifications. The descendants of one of the brothers will be found in the current Peerage Books, and those who know their peerage history well will recognise the case I allude to. All the brothers and sisters had the same arms exemplified, each with a bordure wavy of a different colour. If there were descendants of any of the sisters, those descendants would have been entitled to quarter the arms, because the illegitimacy made each sister an heiress for heraldic purposes. This is a curious anomaly, for had they been legitimate the descendants would have enjoyed no such right.
In Scotland the mark of illegitimacy for the arms is the bordure compony, which is usually but not always indicative of the same. The bordure counter-compony has been occasionally stated to have the same character. This is hardly correct, though it may be so in a few isolated cases, but the bordure chequy has nothing whatever of an illegitimate character. It will be noticed that whilst the bordure compony and the bordure counter-company have their chequers or "panes," to use the heraldic term, following the outline of the shield, by lines parallel to those which mark its contour, the bordure chequy is drawn by lines parallel to and at right angles to the palar line of the shield, irrespective of its outline. A bordure chequy must, of course, at one point or another show three distinct rows of checks.
The bastardising of crests even in England is a comparatively modern practice. I know of no single instance ancient or modern of the kind in Scottish heraldry, though I could mention scores of achievements in which the shields carry marks of distinction. This is valuable evidence, for no matter how lax the official practice of Scottish armory may have been at one period, the theory of Scottish armory far more nearly approaches the ancient practices and rules of heraldry
