The name of Merwyn is Celtic in origin, arising from the ancient Britons of Wales. The name's specific origins were derived from the Welsh personal name Mervin, which originally took the form Merlin. The magician Merlin plays an important role in Arthurian legend and is given the attributes of a Celtic druid. He figures prominently in early Welsh writings, and the first full-fledged treatment of him is given in the Libellus Merlini (Little Book of Merlin), a Latin tract written by Geoffrey of Monmouth c. 1135.

Early Origins of the Merwyn family

The surname Merwyn was first found in Wiltshire, where this distinguished Welsh family claim descent from Mervyn Vrych, (Merfyn Frych 'Merfyn the Freckled', Merfyn ap Gwriad 'Merfyn son of Gwriad', Merfyn Camwri 'Merfyn the Oppressor') an 11th century Lord of Anglesey, who settled in Wiltshire on the English Welsh border. He is thought to have died around 844 and was King of Gwynedd from around 825 to his death. He came from a long line of nobility.

Llywelyn ap Merfyn (died 942) was King of Powys, son of Merfyn ap Rhodri, and grandson of Rhodri the Great. His father, Merfyn ap Rhodri (died c.900) was also King of Powis (878-900.) Mystery surrounds his death. Some believe he died due to the incursion into Anglesey by the Viking Ingimundr. Others believe he lost his realm to an invasion by his brother Cadell, King of Ceredigion.

All trace back to Rhodri ap Merfyn (c. 820-878), later known as Rhodri the Great (Welsh: Rhodri Mawr), who succeeded his father, Merfyn Frych, as King of Gwynedd in 844. He is referred to "King of the Britons" by the Annals of Ulster and later as the "King of Wales."

Merwyn 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 Merwyn have included Mervyn, Mervin, Mervyng, Merwin and others.

Migration of the Merwyn 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 Merwyn were found: Andrew Mervine, whose Oath of Allegiance was recorded in Pennsylvania in 1779; Ferdinand Mervyn, who settled in Philadelphia in 1808; and Alexander Mervin, who was recorded as a British Alien in the United States during the War of 1812..

The Merwyn Motto +

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: De Dieu tout
Motto Translation: From God everything.
