This unusual name is of early medieval Northern English and Scottish origin, found particularly in Aberdeenshire. The modern surname derives from a nickname probably bestowed on someone with the reputation of a "do-gooder", a well-intentioned person. The derivation is from the Northern Middle English word "du", do (in Old English pre 7th Century "don"), with "gu(i)d", (Old English "god"), good. The earliest known bearer of the name, as recorded below, went to Prussia in the king's service in 1382. In 1675 one Francis Duiguid was heir to William Duiguid de Auchinhuiff. The modern surname can be found as Duguid, Duiged, Dugget, Dugood, Doogood, Docket, Doget and Duiguid. James Duguid was married to Mary Patrick on the 12th of January 1777, at St. Martin-in-the-Fields, London. The first recorded spelling of the family name is shown to be that of John Dugnde (ballie of Perth), which was dated 1379, in the "Exchequer Rolls of Scotland". during the reign of King Robert 11, known as "The King of Scotland", 1371 - 1390. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.
