The Story Behind Cai
Cai is a name with ancient roots, primarily deriving from the Roman praenomen Gaius. Gaius was one of the most common and oldest Roman given names, famously borne by many prominent figures in Roman history, including Julius Caesar (Gaius Julius Caesar). The name's meaning 'to rejoice' or 'happy' reflects a positive and auspicious connotation.
The Welsh adoption of Cai is a direct descendant of Gaius, likely introduced during the Roman occupation of Britain. It has been used in Wales for centuries, often appearing in medieval Welsh literature and mythology, most notably as one of King Arthur's knights, Sir Cai (Sir Kay in English Arthurian legend). This long history has firmly established Cai as a traditional Welsh name, despite its Latin origin.
