The design of the Arms was agreed and approved by Mr. Thomas Woodcock (Garter King of Arms and Senior Herald in England), who is based at the College of Arms in London.
Thomas Woodcock said:
The technical heraldic description of the Middleton Coat of Arms, known as a ‘blazon’ is Per pale Azure and Gules a Chevron Or cotised Argent between three Acorns slipped and leaved Or. Per Pale means that the Shield is divided vertically with one half blue (Azure) and the other half red (Gules). A Chevron Or means the gold chevron across the centre of the Shield. There arecotises either side of the chevron which are white (Argent). Slipped means ‘with a stalk,’ so the final part of the blazon – and distinguishing feature of the Shield – means three acorns with gold stalks and leaves. Coats of Arms are granted under the Sovereign’s authority. Since the fifteenth century, this has been delegated to three Kings of Arms in England. They now have jurisdiction over England, Wales and Northern Ireland. In Scotland, Coats of Arms are granted by Lord Lyon King of Arms. Like all applicants, Mr. Middleton started the process by submitting his request to England’s Earl Marshal, The Duke of Norfolk, who issued a warrant to the Kings of Arms agreeing to the granting of new Arms. In this case it fell to Garter and Clarenceux Kings of Arms (two of the three Kings of Arms) to grant the Middleton Coat of Arms by Letters Patent, as the Middleton Family live south of the River Trent, the historic division between north and south in England.
