John H "Jack" McFarland of Titusville PA

John H McFarland was the son of Sarah A and John McFarland of Titusville, PA. He likely went by the nickname "Jack" we believe. He was for some years the proprietor of the Hotel Brunswick in Titusville PA.

He has been identified in this picture as the man with the straw hat and the bow tie. We have no idea who the others in this picture might be. Any help for other identies would be much appreciated.
