Trace Clan Wallace from the Ayrshire and Renfrewshire country of Sir William Wallace across the Atlantic, from the great Scots-Irish migration to America to Lew Wallace, the Union general and author of Ben-Hur, Henry A. Wallace, the 33rd Vice President of the United States under Franklin D. Roosevelt (1941 to 1945), and DeWitt Wallace, the founder of Reader’s Digest. Five waves of migration and six representative Wallace journeys.
