Ignacio Manjarres was a rancher in Florence as early as 1898, when a brand was registered in his name with the county. He was a charter member of the Pinal County Cattle Growers Association. At various times he raised sheep and pigs, fruit trees and vegetables. In 1910, he bought a large lot and built an L-shaped adobe house with 3-foot-thick walls on the property line, typical for Florence. He wanted extra room so his large wood-hauling wagons could turn around. As his family grew, additions changed the home's original dimensions. The house is listed on the National Register of Historic Places.
