William Michael Gilbert Aka Robert E Lee, Bobbie

From Wikipedia about Gilbert, AZ:

Gilbert owes its beginnings to William "Bobby" Gilbert who provided land to the Arizona Eastern Railway in 1902 to construct a rail line between Phoenix and Florence, Arizona. In 1912, many Mormons who had fled the Mormon colonies in Mexico due to the actions of the forces of Pancho Villa settled in Gilbert. By 1915, they began holding church meetings at the Gilbert Elementary School. In 1918, they were organized into the Gilbert Ward.[10]

Incorporated in July 1920, Gilbert was primarily a farming community fueled by the rail line and construction of the Roosevelt Dam and the Eastern and Consolidated Canals. It remained an agricultural town for many years and was known as the "Hay Capital of the World"[11] from 1911 until the late 1920s.
