County Donegal  : Old Age Pension/Census Returns

In 1909 the Old Age Pension was introduced in Ireland but elderly people had to prove that they were over 70 in order to claim it. Since birth certificates had not been introduced until 1864, this in effect meant applying to the authorities in Dublin, who held the 1841 and 1851 censuses, and asking if your name was recorded therein. The letters are stored in large binders in the Public Records Office in Belfast.
