There is no known saint named Sky in any major Christian tradition (Catholic, Orthodox, Protestant).

It's possible there might be a local or folk saint with that name, but that would be a very uncommon occurrence.

If you're looking for a saint, perhaps you can provide more information about what you're looking for:

* Are you looking for a saint with a specific attribute? For example, are you looking for a saint associated with the sky, weather, or a particular area?

* Are you looking for a saint with a particular name or origin?

This information would help to narrow down the possibilities and find a saint that fits your needs.
