The car looked like it might be a Marion Bobcat, so, with that in mind, I discovered the exact picture on the web site "Portal to Texas History", the caption of which says that it is a: "1910 Marion Bobcat". This caption lists the people in the photograph as:"Bill Jones; Cap Rich; Charles Crawford; Dr. Charles Costello, DVM; Walter Jones; T.W. "Bud" Davis; Earnest Farmer; A. P. George; Martha Virginia (Hinson) Ansel; ? Hinson or Joe Jones". I also discovered that the Marion Bobcat probably looks like the Stuz Bearcat because, according to an article in Hemmings, Harry Stutz was chief enfgineer at Marion when the Bobcat was designed.
