Historical maps of Ireland are essential for navigating the country’s complex geography and administrative divisions. The first Ordnance Survey (1824–1846) produced highly detailed six-inch-to-the-mile maps, showing townlands, roads, and even field boundaries—ideal for locating rural ancestors. Earlier estate maps, Down Survey maps (1650s), and 18th-century county maps offer insight into land ownership and political shifts. Griffith’s Valuation (1847–1864), when paired with contemporaneous maps, allows researchers to pinpoint family holdings at the townland level. Given Ireland’s turbulent history of emigration, land redistribution, and record loss, maps provide a reliable framework for reconnecting people with places. Archives like the National Archives of Ireland and online platforms host robust map collections, vital for deepening genealogical discoveries.
