My 14-yr old son is named Deontay (pronounced pretty much the same way). I adopted him and that was his birth name. His mn is
James. I didn't like it at first but I love it now as my son is very cool, although I would prefer to spell it the way you have mentioned. Or even have gone with
Dante.
But my son LOVES his name and is glad it wasn't changed!
He is VERY proud of his name!
