Welsh surnames often reflect the rich history and culture of Wales. Many surnames are patronymic, meaning they are derived from the father's name, with the prefix "ap" or "ab" indicating "son of." For example, the surname Ap Rhys means "son of Rhys." This tradition highlights family lineage and connections. Additionally, some Welsh surnames are derived from geographical locations, occupations, or personal characteristics. Names like Jones and Williams are common, with Jones originating from the given name John. Understanding these surnames provides insight into Welsh heritage and the significance of family ties in Welsh culture.
