I'd be more worried about the motives of the one doing the searching than the fact that the marriage is unlisted.

Maybe it’s not listed, but doesn’t mean it’s an invalidated marriage. What’s weird is someone else looking for someone’s marriage status online. My ex sister-in-law looks for my brother’s marriage status online and it’s creepy.

No we went out of town

I married outside of the USA to a foreign national, so No.

I wouldn't know.. are you talking about your own marriage or someone else's?

What’s the purpose of the person searching that?
