The surname Cadogan is a Welsh name of old Celtic origin, derived from the personal name Cadogan. This name was originally Cadwugaun in the Old Welsh language. Early Origins of the Cadogan familyThe surname Cadogan was first found in Merionethshire (Welsh: Sir Feirionnydd), made a county in Northwest Wales in 1284, and anciently part of the kingdom of Gwynedd, where they claimed descent from the ancient princes of Wales. Of note was, Cadwgan ap Bleddyn (1051-1111), Prince of Powys; Cadwgan ap Meurig (fl.1045-1074), King of Gwent (1063-1074) and Morgannwg; and Cadwgan of Llandyfái (died 1241), a Welsh cleric, Bishop of Bangor (1215-1236.)

Cadogan Spelling VariationsWelsh surnames are relatively few in number, but they have an inordinately large number of spelling variations. There are many factors that explain the preponderance of Welsh variants, but the earliest is found during the Middle Ages when Welsh surnames came into use. Scribes and church officials recorded names as they sounded, which often resulted in a single person's name being inconsistently recorded over his lifetime. The transliteration of Welsh names into English also accounts for many of the spelling variations: the unique Brythonic Celtic language of the Welsh had many sounds the English language was incapable of accurately reproducing. It was also common for members of a same surname to change their names slightly, in order to signify a branch loyalty within the family, a religious adherence, or even patriotic affiliations. For all of these reasons, the many spelling variations of particular Welsh names are very important. The surname Cadogan has occasionally been spelled Cadogan, Cadagan, Caddagan, Caddigan, Cadigan, Cadougan, Cadwgan and many more.

Emigration to New Zealand followed in the footsteps of the European explorers, such as Captain Cook (1769-70): first came sealers, whalers, missionaries, and traders. By 1838, the British New Zealand Company had begun buying land from the Maori tribes, and selling it to settlers, and, after the Treaty of Waitangi in 1840, many British families set out on the arduous six month journey from Britain to Aotearoa to start a new life. Early immigrants include: Cadogan Settlers in New Zealand in the 19th Century- Mr. Cornls Cadogan, British settler arriving as Detachment of the Royal New Zealand Fencibles travelling from Gravesend aboard the ship "Sir George Symour" arriving in Auckland, New Zealand on 26th November 1847 3

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.
Motto: Qui invidet minor est
Motto Translation: He that envies is inferior.
