Esther Bowen (Mrs. Steven Baker) died 02 March 1919 in Cedar township, IA (Iowa Deaths and Burials, 1850-1990).
Her husband may have died earlier but I didn't find a record of his death:
Gladbrook Tama Northern, "The Laborer's Friend"
Official Paper of the City
Friday, February 25, 1887
On Sunday, February 20, 1887, Grandmother Bowen, mother of Willard Bowen of Kansas and Mrs. Steven Baker, with whom she lived, was buried at the Conant school house.She was 74 years old.
Since her death, Steven Baker has grown dangerously ill from the general debility of his system.
