Origin: (Welsh, Welsh Mythology)
Pronunciation: (DIHLahn (English), DAHLaen (Welsh))
It is a decent name though and I do however love the meanings and Welsh Mythology surrounding this name. For those that are thinking of using this I could see a bad boy / warrior type character being named this or the total opposite a very nerdy character being named this. This is a very versatile name with a good long history, so it would fit well in many different genres and eras.
