On 30 June 1922, the historic Four Courts complex on Dublin’s River Liffey was heavily shelled during the Irish Civil War. At the time, The Public Records Office of Ireland, home to centuries of Irish records, was housed within The Four Courts. During the conflict explosives were detonated inside the record treasury destroying millions of Irish records forever. The loss of such significant collections has made researching family history in Ireland more challenging than it is in other countries, but it’s far from impossible.
