About Northern Ireland, Valuation Revision Books, 1864-1933

This collection contains land valuation records from Northern Ireland between 1864 and 1933. Revision books wtook the form of chronological ledgers and tracked changes to a property's original valuation. Valuations were conducted annually.

Using this collection

Records in the collection may contain the following information:

  • Names of property owners
  • Names of occupants
  • Description of property
  • Changes in acreage
  • Changes in property valuation
  • Name of street
  • Name of city, county, parish, and townland
  • Name of affiliated poor law union
  • Date of notation
  • This collection contains a wealth of useful information to help trace your ancestors. As valuation revisions were conducted yearly, you can use them to create a chronological family history. There are no surviving censuses for Ireland prior to 1901, which makes the collection even more useful. Records can even be used to confirm dates of emigration or death, as you can seamlessly trace your family member's address. If you wish to trace your family back even further, you may wish to pair this collection with Griffith's Valuation..

    You may also wish to consult historical maps if you are having trouble locating a historic location. Borders may have shifted, and the names of towns and counties may have changed over time. This is especially true of Ireland, as place names were anglicised by the first Ordnance Survey. For example, the town of Clonmel was originally named Cluain Meala.

    Most volumes, with the exception of those from Belfast, will contain an index that lists the names of towns, cities, townlands, parishes, and poor law unions within the county and their associated page number. The page number listed may not be accurate as notations were continuously updated. If you are looking for a property listed in an urban area, you may wish to browse by street name.

    Every year, new revisions were noted by a different color of ink. Notations were often dated, but in the event you can't find a date, you may be able to calculate the year by the colour ink used.

    The head of household is usually the only one listed, so it is rare to find women and children on the record. If you're looking for a specific family member, try searching for relatives that may have been considered the head of their household. Keep in mind that many of the names in this collection were abbreviated or written in shorthand. While abbreviations weren't standardised, some may be more common. "John" is often abbreviated as "Jno," while "George" may often be written as "Geo."

    Collection in context

    This collection was founded on original data collected by Griffith's Valuation. Conducted between 1848 and 1864, Griffith's Valuation was a country-wide land survey that assessed every land parcel in Ireland. The data collected allowed for a unified, consistent taxation system as well as an impeccably accurate map. After the initial survey, valuation revisions were conducted annually, and the data was collected in a "Current Land Book". Current Land Books are valuation ledgers with new notes written directly next to the original record. When the ledger was full, it became known as a "Canceled Land Book" and a new ledger was used in its place. This system was used until the early 1930s.
