Surname Gwynllyw - Meaning and Origin

Gwynllyw: What does the surname Gwynllyw mean?

The last name Gwynllyw (also spelled Gwynllywy or Gwynllywyd) is a Welsh patronymic surname meaning "descendant of Gwynllyw" or "son of Gwynllyw". Gwynllyw was a sixth century Celtic chieftain and saint from the region of South Wales known as Gwent.,

The original Gwynllyw was said to be descended from a line of Welsh royalty that led up to one of the greatest of Welsh kings, Brychan Brycheiniog, and was the father of the legendary Welsh saint Saint Cadoc from the 6th century. Gwynllyw's own father is thought to have been the Welsh warrior prince, Glywys, and it is likely that Gwynllyw was accredited with the very beginnings of Christianity in the Gwent region.

Gwynllyw's own name is thought to be derived from the Celtic gwyn meaning “fair” or “holy” and llwyd meaning “grey”.This could indicate that he was a fair-haired man with a grey beard, or it might mean he came from a long line of men known for their wisdom.

Gwynllyw is also known to have been a religious ruler and was the founder of a chapel and the first church in Caerwent, which remains standing to this day.

Those who bear the name Gwynllyw today are descended from this legendary Welsh saint and are the living histories of their family and culture. They carry on the legacy of Gwynllyw, a man who was held in high esteem for his religious philosophy and dedication to protecting and nurturing his people through the introduction of faith and the establishment of a religious centre in Gwent.
