Merrow History, Family Crest & Coats of Arms
The ancestors of the Celtic name Merrow 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 Merrow is ultimately derived from the Latin personal name Mauritius, which means "dark."  In Britain, Maurice was the learned form of the name, while Morice was the common form.
Early Origins of the Merrow family
The surname Merrow 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.

Merrow Spelling Variations
Welsh 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 Merrow has occasionally been spelled Merrick, Merick, Meyrick, Meynik and others.
