Find your ancestors in Census, Land & Substitutes

Researching Irish family history has been made more challenging due to the destruction of all census records since 1821 except those dating to 1901 and later.

You will find the fully surviving 1901 & 1911 Irish censuses on Findmypast.

We provide census substitutes to help you fill in the missing gaps. We have fragments dating from 1749 to 1901, as well as 19th century electoral registers and land surveys.

Early Census and Census Fragments

Anyone researching their 19th century Dublin ancestors will find a wealth of information in the 1851 Dublin City Census, which includes names and address of approximately 59,000 heads of households.

We also have the 1749 Census of Elphin, which lists all households, names of household heads, their addresses, occupations, numbers of children, adults and servants, by age and religious denomination – a remarkable document for such an early date. This record set is particularly useful for those with ancestors from counties Galway, Roscommon and Sligo.

The Dublin City Census 1901: Rotunda Ward gives details of 13,556 people residing in 1,334 properties across a 67-street space of the Rotunda Ward area of the city.

Land Surveys also provides you with exclusive online access to the Landed Estate Court Rentals. These records offer a wealth of information about land occupation in the mid-19th century. Originally published to organise the sale of bankrupt estates these records contain information about tenants, rented lots, tenancy terms, and boundary maps. Over 500,000 tenants are included in this collection, and it deals with more than 8,000 estates around the country.

Griffith’s Valuation is another valuable census substitute. It contains information about households that lived through the Famine period and up until the start of the civil registration in 1864. While Griffith's Valuation is available on a number of websites, the version you can search on findmypast Ireland is the one developed by Eneclann Ltd, OMS Services and The National Library of Ireland and is the most complete Griffith's Primary Valuation of Ireland which includes all revisions and amendments

The 1831 Tithe Defaulters compilation records the main data that survives about the people involved in the Tithe War.

Electoral Registers

Electoral registers are an important source of information for family history research. The Reports from Committees, Fictitious Votes (Ireland), Select Committee on Fictitious Votes, 1837-1838 lists those eligible to vote in Ireland after the electorate had been greatly increased following the Great Reform Act of 1832. It contains 52,600 names, with details of occupations, addresses and entitlement criteria to vote.
