The entire family welcomes Sophie's cousin Jacob, the last of her family to arrive in America to start a new life. Everyone pitches in to show him the treats of living in Brooklyn, with Grandma almost hysterically determined that he be happy. But she refuses to let Alan and Nathaniel know that he lost his wife Anna and two sons Josef, age fifteen, and David, age eleven, to the concentration camps. It turns out Grandma has always felt guilty for somehow not making Jacob and his family leave Poland before the Nazis invaded.

When the family learns Katie's sister is pregnant and she and her husband are moving to California where he has a good job, they help Katie plan a shower for her, but Lieutenant Monahan is still hurt that Colleen was not married in the Church. But a chat with Cousin Jacob, who has taken a job painting the Monahans' apartment, may convince him of what's really important. In the meantime, Nicholas and Sid teach George and Jules the finer points of betting on the ponies.
