Including a new preface by the author, this work probes beyond the aggregate statistics of most studies of the migration process. Bruce Elliott traces the genealogies, movements, landholding strategies, and economic lives of 775 families of Irish immigrants who came to Canada between 1815 and 1855 from County Tipperary, Ireland. He follows his subjects not only from Ireland to Canada but in their subsequent movements within North America. His work should be of interest for discussions of 19th-century society in Ireland, Canada and the United States.
