Meaning and background

The story behind Cai

Cai has at least two distinct name histories in Behind the Name’s main reference. In rare Swedish and Danish use it is a variant of Kai. In Welsh mythology and Arthurian tradition it is the Welsh form of Kay. The shared spelling does not make those histories identical. A Scandinavian family connection and an interest in Arthurian literature would therefore be different, documented reasons for choosing Cai.

Origin
Rare Swedish and Danish variant of Kai; independently the Welsh Arthurian form of Kay. Source · Source 2
