What boys names could Ozzy be a nickname for?

[Allium16]

Have always liked the nickname Ozzy since going to college with a lovely Ozzy. Can only think of Oswald as a full name though, which is a no from me.

Are there any other names which could reasonably be shortened to Ozzy?

The one I know is Austin but Oscar would also work. I've also heard of a José who ended up as Ozzy when he settled in the English countryside!

Oisín is a boys Irish name . It is pronounced Usheeen and means “ little dear - the forest animal ! It can be shorted to the pet name “Ush” . My ds is an Oisín

August?

Oscar is the obvious one to me, but you've had some great suggestions.
I'd never have thought of Austin but it works.

Osgood. Osgood Mackenzie was a Scottish landowner and the creator of a famous garden at Inverewe, near Poolewe in Wester Ross.

I know two - one is Oscar and the other is surname Oswald
