The origins of the Welsh name Guilliams go back to those ancient Celts known as the Britons that once occupied the hills and Moors of Wales. This old Welsh surname is from the personal name Gwilliam, which is a Welsh form of the name William.

Early Origins of the Guilliams family

The surname Guilliams was first found in Chirk, where they held a family seat from very ancient times, some say well before the Norman Conquest and the arrival of Duke William at Hastings in 1066 A.D.

Guilliams 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 Guilliams has occasionally been spelled Gwilliam, Gwuilliam, Guilliam and others.
