Possibly this is Henry Rhodeman/Rhodman. Henry was born abt. 1810, in MD. He married Sidney Keller, who was born abt. 1812-1816. They lived in Pendleton County, VA.
Written on the back of the photo: Grandad Rhodeman, 97 years old when he died, born 1810, died 1907 at Evanw (the rest is torn off) West Virginia. The photo was originally attached to a backboard. The writing on the back would have continued, but whatever was there originally came off with the backboard. Evanw (which is one of the words cut off) could have been Evanwood.
Do you know more about the Rhodemans? Please let me know.
