context: The company was founded on November 26, 1905, when Florence Butt opened the C.C. Butt Grocery Store on the ground floor of her family home in Kerrville, Texas.[11] In 1919, Howard Edward Butt, Florence's youngest son, took over the store upon his return from World War I. Shortly after becoming owner of his mother's small store, Howard tried four expansions into Central Texas, including one in Junction, all of which failed. Finally, in 1927, Howard launched a successful second store in Del Rio, Texas, followed by the purchase of three grocery stores in the Lower Rio Grande Valley. The first initials of Howard E. Butt became the name of the store.[12]
