Thomas F. McMillan (also spelled McMillon) was the father of Flagstaff. Born in Tennessee, he sought gold in California and raised sheep in Australia before moving to northern Arizona in 1876. Here he established a sheep ranch and farm just north of the present city. He prospered and became one of the leading stockmen of Arizona. It was at a spring he used as a sheep camp on July 4, 1876, that the Second Boston Party raised the flag staff that gave Flagstaff its name.

McMillan played an important part in the development of Flagstaff. When Coconino County was formed in 1891, he was elected chairman of the Board of Supervisors and helped the county through its formative period. He was the first Postmaster and was a member of the first library board. In 1888 he bought the shell of this building, begun by others in 1887, and completed it.

His first tenants were a bank and a hotel. In 1892 the hotel became the terminus for the Flagstaff-Grand Canyon Stagecoach (see photo). The McMillan Opera House, located on the ground floor, became the premiere place in town to host plays, dances and other events.

The McMillan family moved into the hotel and was living there in 1906 when Thomas F. McMillan died. His widow, Kate, ran it until her death in 1923. Her daughter, Mary "Mamie", married George Fleming in
