Searching for emails attached to a contact?

Searching for emails attached to a contact?

I'm looking for meeting notes for a contact at a company that would have been attached to the record by attaching an email.  I know the company, but I can't remember the persons name (and we have more than a hundred contacts at this company) is there a way to search or sort contacts by most recent modification (including a modification like attaching an email from Outlook to a contact).  Any other suggestions for how I would find these notes?
