This chapter presents data-intensive method that provides detailed depictions and geographical analyses of the long-term multiple generation migration trends to analyse migration geographies of Europeans to the America from the 1600s to 1900. Genealogical records also illustrate the profound importance of family relationships in fashioning historical migration streams and settlement characteristics. The interconnection of place and people has a most peculiar manifestation in the imprint of families on particular spots over extended periods. The unveiling of a family history spanning numerous generations reaches out across space and time to reveal the greater historical trends of the world. The main interest here in genealogical geography is in what way genealogical data provide means to view past family and community geographies. Generational migration forward in time has a more varied numerical basis. The approach integrates a number of methods to extract straightforward summary measures from the expansive data available in the FamilySearch 'Family Tree' system.
