Pup or victory of the people
Kolyn is a modern spelling variant that likely draws from two distinct roots. It is often used as a creative variation of Colin, which can be a Scottish diminutive of Nicholas, meaning 'victory of the people', or derived from the Gaelic word 'cuilean' meaning 'pup' or 'cub'.
