Welcome to Coolattin Lives. The Coolattin Estate covered 85,000 acres in south Co. Wicklow. Generations of families rented farms and cottages from the Fitzwilliam family (later Wentworth-Fitzwilliam). As progressive landlords, the Fitzwilliams kept careful records of their tenants throughout the 19th century. Between 1847 and 1856 the landlord assisted hundreds of families to emigrate to Canada. In Coolattin Lives thousands of tenant records have been transcribed, digitised and mapped allowing descendants of these tenants – in Ireland, Canada and around the world – to trace their ancestors, find the district where they lived, and make their way back to the family home place.
