Dr. O.L. Mahoney, the efficient superintendent of the county hospital at Phoenix, was born March 7, 1839 in Jefferson County, Tennessee... Source: A historical and biographical record of the Territory of Arizona. Chicago : McFarland & Poole, 1896 (aka History of Arizona, 1896): Dr. O.L.Mahoney, the efficient superintendent of the county hospital at Phoenix, was born March 7, 1839 in Jefferson County, Tennessee, being the eldest of a family of ten children born to the marriage of Dr. James W. and Amanda M. (Turnley) Mahoney, who were also natives of Tennessee. His great grandfather was one of the colonies' defenders during the struggle for independence from Great Britain and his maternal grandfather was a soldier of the war of 1812, participating in the battle of New Orleans under General Andrew Jackson. Dr. James W. Mahoney practiced medicine many years in his native state, moving, afterwards to Arkansas. His death occurred at Pine Bluff after a long and honorable life. The immediate subject of this sketch, Dr. O.L. Mahoney, received a liberal education and began the study of medicine when yet in his teens. In 1861 he became a member of Company C. Ninth Arkansas Volunteer Infantry. During the time of his enlistment Dr. Mahoney was in active field service and witnessed some of the most hotly contested battles of the war, among them being Belmont, Corinth, Shiloh, Prairie Landing, Little Rock and Arkansas Post. The literary education of Dr. Mahoney was acquired at Pine Bluff, White Sulphur Springs and at St. John's College at Little Rock, his professional learning was from the Medical College of Ohio from which he was graduated in 1867. Prior to this time, however, he had practiced medicine. His first location was at Murphysboro, Illinois, but after a residence there of but a few months he attached himself to an emigrant train that was conveying many cattle to the great West. With this protection from depredating bands of Indians he got as far west as Maricopa Wells, where he parted from the caravan and from which point he pushed on to Wickenburg, then having a population of about 350 and being one of the most important points in the Territory. After a residence at this place of about one year he returned to Murphysboro, Illinois, where he was actively engaged in medical practice until May 1883 when he located permanently at Phoenix. In 1837 he was selected to remove the Arizona insane patients from the asylum at Stockton, California to the new asylum at Phoenix and served as the first superintendent. In 1883 he was appointed superintendent of the county hospital, served four years, and was re-appointed to the position in 1891 and is still serving in that capacity. Dr. Mahoney is among the well-known men of the Territory, has filled various positions of honor and trust with signal ability and satisfaction to all concerned and is a member of the Odd fellows and Ancient Order of United workman. In 1870 he married Miss Virginia Rasson, a lady of high attainments, a graduate of the Women's College, Chicago who was born in Tennessee.

Evans House History. About 1940, the historical American Buildings Survey conducted a survey of Phoenix to identify buildings of outstanding historical or architectural significance. Of those buildings selected only two remain standing; one is the Rosson House, the other is the Evans House which is located at the intersection of Eleventh Avenue and Washington. ... In 1908 the home was purchased by Oscar L. Mahoney for $6,000. Mahoney and his wife, Virginia, are probably the most notable people to have been associated with the development and occupation of the "Evans House". Both were doctors; he an 1867 graduate of the Medical College of Ohio, and she an 1883 graduate of the Women's Hospital Medical College of Chicago. The Mahoneys settled permanently in Phoenix in 1883 where they distinguished themselves in both joint practice and in singular situations. Oscar is best known as the first superintendent of the Territorial Insane Asylum. He also held positions as a city councilman, county coroner and superintendent at the County Hospital. Virginia was one of twenty-one women who filed diplomas from legitimate schools of medicine with county recorders during the territorial years. She was one of only four of these women to be licensed to practice by the medical examining board established in 1903. On April 27, 1910 Mahoney transferred the title to the house and property to his wife, Virginia, for "Love and Affection". He died in 1915; she in 1925 [in April 1924 per JAMA obituary], after which the house was sold to the Odd Fellows. Mrs. Gertrude Conway sold the house to the State of Arizona and in 1982 the State leased the house to the Arizona Architects Foundation. Source: http://www.lib.az.us/extension/evans.cfm
