Young creature or boy
Collen is a Welsh name derived from the word 'collen', which literally refers to a hazel tree or sapling, but is often interpreted as 'young creature' or 'boy'. In Welsh history, it is associated with Saint Collen, a 7th-century monk who founded a church in Llangollen. It is distinct from the more common Irish name Colin, though they share a similar phonetic appeal.
