Over the past 400 years thousands of people have moved to settle in Britain, and thousands more left its shores for life overseas. This practical and accessible guide shows how to explore migration records - and ancestors feature in them - through the wealth of records at the National Archives and elsewhere. Moving On charts new online releases, naturalization applications, and discusses how improved catalogue information has opened up passport applications for research. From refugees fleeing persecution to child migrants, naturalization and citizenship papers to transportation records, it is an invaluable guide to the story of migration that changed so many lives.
