The cemetery is on a hill and you enter halfway up; Whitmore is the second row from the bottom in the furthest section from the gate, grave # 363.

A standard French Military grave marker; a white cross with an inscribed centerpiece. 

Frank Whitmore was born near Ellsworth, Maine, on May 21, 1876, the son of Charles Whitmore, a farmer. He went to Virginia as a young man, and worked for years on the Old Dominion Line boats. With money he had saved, he bought a farm on the James River, near Richmond, and was a successful poultry farmer until the war called him to France and death.

"I can truthfully say that Whitmore never knew what fear was. That is why he sleeps peacefully to-day in a little grave with the colonel of the Legion. If he had not been the man he was, he would have been in a hospital instead of in the grave".
