This book is based on the two surviving registers of passports issued by the departmental government between 1837 and 1844 for travel outside of France. The author has culled nearly 2,000 records from the registers for persons whose destination was the U.S. Also included is a select group of emigrants whose destination was given as Hamburg or London, cities which often were intermediate destinations in unreported emigration to America. Each entry gives the name of the emigrant, age, place of birth, places of residence and destination, profession, accompanying family members, and the entry number and date from the passport register.
