Taken in the years 1656-1658, the Down Survey of Ireland is the first ever detailed land survey on a national scale anywhere in the world. The survey sought to measure all the land to be forfeited by the Catholic Irish in order to facilitate its redistribution to Merchant Adventurers and English soldiers. Copies of these maps have survived in dozens of libraries and archives throughout Ireland and Britain, as well as in the National Library of France. This Project has brought together for the first time in over 300 years all the surviving maps, digitised them and made them available as a public online resource.
Griffith ’s Valuation is the name widely given to the Primary Valuation of Ireland, a property tax survey carried out in the mid-nineteenth century under the supervision of Sir Richard Griffith. The survey involved the detailed valuation of every taxable piece of agricultural or built property on the island of Ireland and was published county-by-county between the years 1847 and 1864.
The Tithe Applotment Books are a vital source for genealogical research for the pre-Famine period, given the loss of the 1821-51 Census records. They were compiled between 1823 and 1837 in order to determine the amount which occupiers of agricultural holdings over one acre should pay in tithes to the Church of Ireland (the main Protestant church and the church established by the State until its dis-establishment in 1871). There is a manuscript book for almost every civil (Church of Ireland) parish in the country giving the names of occupiers of each townland, the amount of land held and the sums to be paid in tithes.
The Census reports are the official compilations of population figures which also contain various other statistics. The primary units used were counties and baronies. The first official Census of Ireland, 1813 – 1815 is incomplete, however the 1821 census is more comprehensive. Data was collected on houses, inhabitants, ages, occupations, farm size. The Census also provides information on emigration and statistics on education and literacy some of which comes under the heading “observation”.
The standards of the 1831 Census are lower than that of 1821, however by far the most reliable for the first half of the 19th century is that of 1841. It is arranged by county and provides Tables of ages, education, marriage, house accommodation and occupations. For Offaly search for King's County.
The Ordnance Survey was established in the Phoenix Park, Dublin, 1824 and assigned the task to delimit the 60,000 townlands in Ireland. This was completed in 1846 with a total of 1,906 sheets produced. The maps are a scale of six inches to one statute mile with supplementary large scale maps. Boundaries of counties, baronies, civil parishes and townlands defined.
