The ancestors of the Celtic name Merock 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 Merock 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 Merock family

The surname Merock 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.

Merock Spelling Variations

There are relatively few surnames native to Wales, but they have an inordinately large number of spelling variations. Early variations of Welsh surnames can be explained by the fact that very few people in the early Middle Ages were literate. Priests and the few other literate people were responsible for recording names in official documents. And because most people could not specific how to properly record their names it was up to the individual recorder of that time to determine how a spoken name should be recorded. Variations due to the imprecise or improper recording of a name continued later in history when names originally composed in the Brythonic Celtic, language of Wales, known by natives as Cymraeg, were transliterated into English. Welsh names that were documented in English often changed dramatically since the native language of Wales, which was highly inflected, did not copy well. Occasionally, however, spelling variations were carried out according to an individual's specific design: a branch loyalty within the family, a religious adherence, or even patriotic affiliations could be indicated by minor variations. The spelling variations of the name Merock have included Merrick, Merick, Meyrick, Meynik and others.

Migration of the Merock family

Many Welsh families joined their Scottish and Irish neighbors during the late 1800s and early 1900s in seeking refuge in North America. Like the Irish and Scottish, many Welsh anxiously awaited the work, freedom, and opportunities that they believed lay in North America. Those who did journey over to the United States and what became known as Canada often realized those dreams, but only through much toil and perseverance. Whenever and however these Welsh immigrants arrived in North America, they were instrumental in the creation of the industry, commerce, and cultural heritage within those two developing nations. In the immigration and passenger lists a number of early immigrants bearing the name Merock were found: 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.
