The age of innocence is that period between 1945 and 1965.
World War II has just ended, and thousands of servicemen are returning from home.
Some, as in the case of Frank Stoneman, are returning home to wives and children they have not seen for more than three years.
Frank, Thelma, and Earl live in a small house in Pasadena when Bruce arrives on the scene.
The family moves to nearby Azusa, and a third son, Jack, makes his debut.
Thelma has kept a photo album for each of the three.
