Biography
Early years
Frederic O. MacCartney was born November 2, 1864, in the town of Prairie du Chien, Wisconsin, the county seat of Crawford County, located in the rural southwestern corner of the state. His parents, Alexander MacCartney and the former Mary M. Jones, moved the family briefly to Denver, Colorado, when Frederic was six, before settling down for the next 13 years in Storm Lake, Iowa.
Very religious from the time of his youth, at the age of 17 MacCartney determined to dedicate his life to the Christian church. He attended Iowa College, now known as Grinnell College, from which he graduated in 1889. Thereafter he entered the Andover Theological Seminary in Andover, Massachusetts, finishing there in 1893. Originally a Congregationalist, MacCartney switched his religious affiliation to Unitarianism at this juncture.
MacCartney was married in 1889, but his wife died after just six months of marriage. He never remarried.

The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Jul 23, 2026.
