In some ways, the Good Will Home became a family affair. Hinckley ran the school-home-farm from its beginnings in 1889 until 1919, when his son, Walter, took over supervisory duties.
Hinckley's wife, Harriett Palmer Hinckley, concentrated on raising the couple's four children: Alice, born in 1881; Walter, 1885; Edward Benjamin, 1887; and Faith, 1891.
Hinckley's sister, Jane Hinckley, was the first matron, serving until her death in 1914.
His daughter Faith worked at Good Will for many years and Walter's daughter, Harriet Hinckley Price and her husband, Donald Price, whose parents also had worked at Good Will, worked at the school until the 1950s.
