The builder of this residence was the second of three Butte men of the same name. The elder A. J. Davis (1819-1890) was said to have been Butte’s first millionaire and founded the predecessor to the First National Bank of Butte in 1877. His nephew Andy, the second A. J. Davis (1863-1941), started with the bank in 1882, became president in 1890, and inherited his uncle’s fortune. Andy and his brother, John E. Davis, built these twin homes in 1891. Andy’s son, the third and youngest A. J. Davis, later lived at 805 W. Broadway. The twin residences share a sidewalk entry and a roof connecting the side porches. These common features were added some time after the original construction. Hardwood floors with inlaid border designs grace four rooms of this home and one room of its twin. A portion of this residence’s third floor was finished to serve as maids’ quarters. The elaborate two-story brick carriage house to the east features an elevator used to move carriages and sleighs to and from second-floor storage, and a groomsman’s apartment spans the front of its upper floor.
