Isaac Coston traveled west in 1862 after being admitted to the bar in New York. Upon settling in the Boise area, he entered into a farming partnership with Frank C. Ghost and J.W. and Solomon Maynard. Their farm was where the Barber Lumber Mill now stands.
Coston's first wife was his partner's sister Wealtha Maynard. Five years after her death in 1867, he married Mary Drake. Both wives and three of his five daughters are buried in Pioneer Cemetery.
Between the years 1870-1883, Coston served four terms in the territorial legislature, and was a member of the constitutional convention in 1889. Coston was master of the Masonic Lodge No. 2, active in Native American affairs, and served as a member of the board of trustees of the state insane asylum at Blackfoot.
