Kniffel's search for a connection to Poland is propelled by memories of the stories his grandmother told him about her emigration to Michigan in 1913. While his family eludes him, the adventure becomes an investigation into the relationship between mothers and the legacy they give their sons.
Poles who emigrated to America, the author concludes, must have been particularly good at assimilating into American culture. Less than fifty years after his maternal grandparents arrived in the United States, barely a trace of their Polishness existed in their grandchildren. Through his grandparents' struggles, their children became American and created a new world for themselves and their descendants.
In returning to Poland himself, Kniffel sought and found a bridge to the "Great Migration" that changed the lives of so many millions--and millions yet to come.
