Is there anywhere to check what devices that we use to have on our Account

There is no list of historical devices you’ve had associated with your AppleID but have since removed.

Check under your Apple ID.

Manage and use your Apple ID - Apple Support

It’s troubling that you say “we use[d] to have on our account”.

An Apple ID should be associated with exactly one person.

I should clarify -

Michael Black is exactly correct. He likely read your question better than I did.

I assumed, probably incorrectly, that you were asking about devices currently associated with your account. That is not how your question was phrased.
