From Dave Price

Six big features: Let's see... there were Tillie, Tony, Clara and Pitt. Who are the two I'm missing?" "When the John Robinson show closed under Robinson family ownership in 1911 they retained the six elephants Tillie, Tony, Pit (Petite), Clara, Ella and Basil (male). For reasons unknown to me they spent the next four years in the Selig Zoo in California.  By 1915 they were down to the four you mention and best remembered from their days in Vaudeville as the John Robinson Military Elephants."
