Show ContentsMirrock History, Family Crest & Coats of Arms

The ancestors of the Celtic name Mirrock came from the rugged landscape of Wales. This old, proud name derives from the personal name Meuric, which is the Welsh form of Maurice. The surname Mirrock is ultimately derived from the Latin personal name Mauritius, which means "dark." 1 In Britain, Maurice was the learned form of the name, while Morice was the common form.

Early Origins of the Mirrock family

The surname Mirrock was first found in Anglesey (Welsh: Ynys Môn), a Welsh-speaking island, and present day County of Isle of Anglesey, located at the northwestern extremity of Wales. The family was traditionally understood to be descended from Mrien, Lord of Rheged, through Cadaval Ynad, a Judge of Powys, who lived about 1190.

The senior branch of the line settled in Anglesey where Samuel Cadaval was Lord of Cydywain. His son, Tudor ap Madoc, married the daughter of the Prince of North Wales. Einiawn Ap David, his successor was Usher at the Palace of Sheen.

Mirrock Spelling Variations

Although there are comparatively few Welsh surnames, they have a great many spelling variations. Variations of Welsh names began almost immediately after their acceptance within Welsh society. In the Middle Ages, it was up to priests and the few other people that recorded names in official documents to decide how to spell the names that they heard. Variations that occurred because of improper recording increased dramatically as the names were later transliterated into English. The Brythonic Celtic language of Wales, known by natives as Cymraeg, featured many highly inflected sounds that could not be properly captured by the English language. Spelling variations were, however, also carried out according to an individual's design: a branch loyalty within the family, a religious adherence, or even patriotic affiliations were all indicated by the particular variation of one's name. The spelling variations of the name Mirrock have included Merrick, Merick, Meyrick, Meynik and others.

Migration of the Mirrock family

Many people from Wales joined the general migration to North America in the 19th and 20th centuries, searching for land, work, and freedom. Like the many other immigrants from the British Isles, they made a significant contribution to the development of Canada and the United States. The Welsh and their descendents added a rich cultural tradition to the newly developed towns, cities, and villages. An investigation of the immigration and passenger lists has revealed a number of people bearing the name Mirrock: Henry Merrick, who settled in Virginia in 1635; Francis Merrick, who settled in Virginia in 1654; John Merrick, who arrived in Barbados in 1680 with his servants.
