Girls must be named Dawn, Dawny, or some variation thereof. Firstborn sons must be named Jon with no "h." Luckily you've already got that covered.
Congratulations, man. And what a great way to do it. Some day your child might wear that same ring. Well, played, sir. I tip my hat to you!
As a fellow 'Jon' I support this message. Don't elope unless this is what the lady really wants. In seriousness, this is one of the most important days of a woman's life. If she wants a big wedding, give it to her.
