Photograph of Sam E. McKnight (1864-1940) seen here (in dark jacket) and logo of the Flying U Ranch on front of card. In the "Men of Texas", p. 1164, Texas State Archives it noted he had been active in the livestock business in West Texas for more than forty years. His ranch properties began in Sutton and stretched to McCulloch County. He was also a director of the First National Bank of Sonora and his ranch home was on the old Junction Highway. He wanted to build fence along the Rio Grande to prevent the importation of cattle infested with ticks which were common in Mexico.
