My unknown ancestor

This old gentleman's picture was found in a box of pictures my grandmother left. It has no name on the back. My grandmother was from Indianapolis originally and then moved to Palo Alto, California.

This photo belonged to my grandmother, Mettie Fitch Bradford who married Jacob William Markley. It was in a box of photos of her Markley and Bradford families so it possible was a grandfather or other relative of hers, thus making her my ancester too. Can you help? Other family names were Fitch and Horton all of Indiana or possibly Ohio
