Irish census survivals and substitutes, 1821–1851
Most 1821, 1831, 1841 and 1851 returns were destroyed in the 1922 fire. Surviving original fragments include Antrim 1851; Belfast one ward 1851; Dublin city heads-of-household index 1851; Fermanagh 1821/1841/1851; Cavan 1821/1841; Cork 1841; Galway 1821; Offaly 1821; Meath 1821; Waterford 1841; and Londonderry/Derry 1831 with 1834 revisions.
The Derry 1831 material includes names of householders and counts by religion and sex, with 1834 revisions. It is not a person-by-person list of every household member. Search transcripts are finding aids; verify the scanned return and record omissions.
Reading the evidence: an index, transcript, provider search page and original image are different sources. A recorded image link does not mean its reading or identity match is confirmed. Inspect the assessment and source page before changing a family relationship. Repository guides checked 4 October 2026.
People in the collected census references
0 reference items · 0 linked catalogue people. Several citations may describe the same household; one return can name several people. Linked people include spouses and relatives and are not a verified count of Glasgow surname entries. This is our collected evidence, not a complete surname search of the surviving census.
0 references have a supported census year; 0 remain unresolved. Years come from the enumeration title or original census URL; access dates, birth years and archive numbers are excluded. Countries identify the census jurisdiction where stated, rather than a person’s birthplace.
Collected references 0
Reference items in this project, not the total surviving archive. A reference can appear in several types or locations; several references can concern the same record. Countries are inferred from source descriptions and recorded places, so check the citation. Undated and ambiguous items remain available.
