1841 Census Fragments

Unlike the two earlier censuses, the returns in 1841 were filled out by the householders themselves, rather than government enumerators.The information supplied was:
  • name;
  • age;
  • occupation;
  • relationship to the head of the household;
  • date of marriage;
  • literacy;
  • absent family members;
  • family members who died since 1831;

Only one set of original returns survived 1922, that for the parish of Killeshandra in Co. Cavan. There are, however, a number of transcripts of the original returns because the returns from 1841 & 1851 were used in the twentieth century as proof of age when the Old Age Pension was introduced.

The forms detailing the results of searches in the original returns to establish age have survived and are found in The National Archives for areas in The Republic of Ireland, and The Public Record Office of Northern Ireland for areas now in its jurisdiction. County by county indexes to the areas covered, giving the names of the individuals concerned, are found on open shelves in the Reading Rooms. Copies of the Northern Ireland returns are also available at the LDS Library.

A number of other miscellaneous copies, some also related to the Old Age Pension, and mostly relating to Northern counties, are detailed (though not indexed) in the pre-1901 census catalogue of the National Archives, on open shelves in the Reading Room. For the counties with significant numbers of these copies, details will be found under the relevant county.

As well as these copies, there are also a number of researchers' transcripts and abstracts compiled from the original returns before their destruction, and donated to public institutions after 1922 in an attempt to replace up some of the lost records. Since the researchers were usually interested in particular families, rather than whole areas, these are generally of limited value. The most significant collections are the Walsh-Kelly notebooks, which also abstract parts of the 1821, 1831 and 1851 returns and relate particularly to south Kilkenny, and the Thrift Abstracts in the National Archives. Details of dates, areas covered and locations for the Walsh-Kelly notebooks will be found under Co. Kilkenny. The Thrift Abstracts are listed in detail in the National Archives pre-1901 census catalogue, under "miscellaneous copies". Counties for which significant numbers exist are given under the relevant county.
