In what time period does the novel, Thy Brother’s Wife, take place?

The novel is set nostalgically within the context of John F. Kennedy's years in the White House. In Greeley's eyes, that era marked a confluence of historical events productive of hope and glory for American Catholics. The Irish had been assimilated enough to send one of their own to the White House, and at the same time Vatican II was stimulating waves of renewed enthusiasm within the international Catholic Church.
