Surname Origins
The surname Mathias in Wales originates primarily as a patronymic name derived from the Biblical personal name Matthias (a Greek/Latin form of Matthew, meaning "gift of God").
It became established in Wales, particularly in Pembrokeshire and South Wales, often evolving from a recurring Christian name into a stabilized surname by the 17th century.
Pembrokeshire Roots: A notable family, the Mathias family of Llwyngwaren, Pembrokeshire, originally used the surnames 'Cole' or 'Young' before adopting Mathias as a surname in the late 16th/early 17th century.
Thomas Mathias (died c. 1617) was key in stabilizing the name in this area.
