Show ContentsWillam Surname History

The Welsh name Willam is a patronymic surname derived from the personal name William, which is in turn derived from the Old German names Willihelm and Willelm (the Norman French version was Guillaume). Following the Norman Conquest of 1066, William became the most popular personal name in Britain for a time.

Early Origins of the Willam family

The surname Willam was first found in Breconshire and Monmouthshire on the English/Welsh border, where they are traditionally believed to be descended from Brychan Brecheiniog who was Lord of Brecknock at the time of King Arthur of the Round Table.

The mediaeval seat of the ancestors of the Willam family was at Llangibby Castle in County Monmouth. More recently, the family is descended through Rhys Goch, the red haired Lord Ystradyw from Caradog Vreichvras.

One of the first records of the name was listed as Robertus filius Willelmi 1 which was listed in the Domesday Book. 2 Other early records include Richard Williams who was listed in the Hundredorum Rolls of 1279 and John Wylyam who was listed in the Subsidy Rolls of Sussex in 1296.

Willam 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 Willam has occasionally been spelled Williams, Quilliams, Guilliam, Guilliams and others.

These immigrants greatly contributed to the rapid development of the new nations of Canada and the United States. They also added a rich and lasting cultural heritage to their newly adopted societies.
