Meaning: there are several possible meanings for the name but nothing concrete, and they may not even be accurate. It’s from a surname denoting someone who came from a place called Denzell in Cornwall. I’ve seen it listed as meaning “fort”, “fertile highland” or “high stronghold”.
I’ve also seen it listed as being a pet form of German name Denz, a short form of personal name Degenhardt from a habitional name from a place called Tenze in Mecklenberg which apparently from an old name of unknown meaning.
And yet again I’ve also seen it listed as deriving from Denisel, a medieval pet form of Dennis, itself the English form of Dionysius, from Greek Dios meaning “of Zeus” + the name Nysa.
