Well, I added the Notables template to his profile, since he qualifies as notable. He also belongs in Category: US Representatives from Ohio.
Some other categories I would add are Category:Marietta, Ohio, Category:Columbus, Ohio, and Category:Newark, Ohio. He seems to have been an important citizen of these three places (and possibly also other places), so another contributor researching someone who lived in those places might appreciate a pointer to this profile.
He also could be placed in Category: Business Owners
