Richard Griffith's Valuation – a mid-19th century gem

In the absence of census returns, Irish genealogy research
for the early- to mid-19th century relies on Griffith's Valuation

Griffith's Valuation

Irish landscape
Richard Griffith's Valuation is one of the great gems among Irish genealogy resources. In the absence of any surviving pre-1901 censuses, beyond a few precious fragments and transcriptions, it is the most comprehensive mid-19th century resource available and can help direct genealogists to the exact plot of land where their ancestors lived.

It was not, however, a census, nor was it intended to be one. Instead, it was a land survey and, as such, it has some limitations because it was not designed to do what we, one and a half centuries later, would really like it to do! That is, locate and deliver our ancestors. If only!

Even so, Griffith's Valuation may be able to move your search on. To get the best from it, it's worth appreciating its purpose at the time it was compiled, understanding the instructions given by Richard Griffiths to the valuers/surveyors who gathered the information, and knowing the year it was carried out in your ancestor's county (see date map).

Griffith's Valuation: its original purpose

sample from
In the early 19th century, taxes were based on property and the methods of calculation varied from county to county. The Government wanted to create a consistent system and needed to find out who its people were and how much they might be able to tax them, so it tasked Richard Griffith, the director of the Valuation Office in Dublin, to carry out a land survey.

The result was Griffith's Valuation – full name The General Valuation of the Rateable Property in Ireland but also known as the Primary Valuation (of Tenements) – a detailed guide of the property, land and households of mid-19th-century Ireland.

It is not a census. It covers who owned what and who rented what, and assessed the value on which each identifiable 'parcel' of land and/or property should be taxed.

Only the head of each household is identified. Family relationships and other personal information were not recorded.

For this reason, few women and no children are included. The very poorest ie those who lived on the verge of vagrancy in makeshift or temporary hovels were also excluded. Their numbers were small.

Griffith's Valuation: its value for genealogists

Surname research

For researchers who don't know where their ancestors lived, Griffith's Valuation can help narrow down locations where their surname was most prevalent and so identify areas for further study.

A printed Index to Householders, showing how many times a particular surname appears in each region, is available in many repositories and can also be readily found online.

View of ASkAboutIreland homepage.However, Ask About Ireland is now the easiest way to search Griffith's Valuation by surname or placename. It's also free to access.

So who is it of use to? Nearly all Irish family historians will find Griffith's Valuation useful, and most will start with the Primary Valuation of Tenements, published county by county across the island between 1847 and 1864. See sample of a page from County Carlow above.

If you don't know where your family lived, you may be able to narrow down the possibilities by finding the parishes where your ancestor's surname was prevalent (see box below).

This can help you identify the most appropriate church registers to start your search. If your ancestor emigrated in the mid to late 1800s, you may find him, her or family at home before he left. Even if he set sail before Griffith's Valuation was published (1847-1864, depending on county) and subsequently married abroad, you should find his father's name on both his marriage certificate and in the Primary Valuation at the ancestral home.

If you already know your ancestors' townland (whether or not they emigrated), Griffith's Valuation will also allow you to collect detailed information about their lives and their neighbourhood. Some of this detail may be found in the Notebooks used by the valuers as they carried out their work, or in the Cancelled Land Books, also known as the Revision Books. See the Valuation Books page.

Each entry in Griffith's Valuation contains:

  • The Ordnance Survey map reference number
  • The townland or street where the property is located
  • The name of the occupier (see box to the right)
  • The name of the immediate lessor ie the landlord
  • A brief description of the property ('house, offices and land')
  • The land area of occupier's holding, in acres, roods and perches
  • The annual valuation of the land and buildings

How is Griffith's Valuation arranged?

The Valuation is arranged by county, barony, Poor Law Union, civil parish and townland (see Irish land divisions if you are unfamiliar with these terms).

All property was included, from the smartest Dublin home.....
Georgian door in Dublin. the humblest rural dwelling
Old farm door.
It lists pretty much every occupier of property in Ireland. In rural areas this meant every dwelling while in urban areas it also meant every household within multiple occupancy buildings ie tenements.

The information collected from each occupier was cross-referenced with the Ordnance Survey map of Ireland so that each individual occupier is identified by townland name (or street address).

In addition, the following details are recorded:

–  the name of the occupier’s landlord ie the person from whom the occupier was renting (immediate lessor)
–  a brief description of the property and its acreage
– a valuation of land and buildings.

Each occupier’s reference can be found on the relevant Ordnance Survey maps (which survive intact). This allows today’s genealogists to identify the exact piece of land their ancestors lived on back then.

Where can Griffith's Valuation be studied?


Like father, like son

The men who worked as Valuers were native-born Irish and understood traditional naming patterns and the use of a father's first name to distinguish between men who had the same name.

In townlands where a surname was common, the Valuers distinguished between individuals in various ways.

Typically, they would add, in brackets after a person's name, the first name of that person's father.

So, for example, John Tobin (Patrick) is the son of Patrick Tobin, whereas John Tobin (Michael) is the son of Michael Tobin.

Where relevant, the abbreviations Snr (Senior, or father) and Jnr (Junior, or son) were sometimes used.

Similarly, occupations were often used as identifiers ie Jeremiah Crowley (farmer) and Jeremiah Crowley (victualler).

Such entries can be a huge bonus because there may be no other document in existence to provide these family connections between the individuals named. They're 'genealogical gold'!

Some 301 volumes, published 1847 to 1864, make up the complete Griffith's Primary Valuation of Tenements. No single repository holds the entire original collection. However, in various states of incompleteness (or even just per county) it may be available on microfiche or photocopy in local and regional libraries across Ireland and at the major institutions in Dublin (the National Library, National Archives and the Valuation Office) and in Belfast (the Public Record Office of Northern Ireland).

The original maps are held by the National Archives of Ireland in Dublin. Scanned images are available at the Valuation Office in Dublin.

Valuers' Notebooks, Cancelled/Revision books and Current Land Books: These are pre- and post-publication manuscript books. They are not a researcher's first port of call, but can be extremely useful for further research after studying the Primary Valuation of Tenements. See link in the Where Next? section.


Griffith's Valuation of Tenements is now widely available online. It is available on Ancestry (in the Irish Wills, probate & tax collection) and FindMyPast as part of their subscription packages, and – for free – on Ask About Ireland (see Surname Research box above).

Original maps – those created as part of Griffith's Valuation – can be viewed at FindMyPast... the only online database to match a searchable Valuation to original maps. Slightly later maps can be married to Valuation searches (free) on AskAboutIreland. Newer still, maps from around 1900 can be viewed free of charge on the Valuation Office's website.

Valuers' Notebooks, Cancelled/Revision books and Current Land Books: Only the Revision Books for Northern Ireland counties are available online. Some of the Valuers/Surveyors' Notebooks are expected to make their online debut on the National Archives of Ireland's genealogy portal in mid-2015. They will simulataneously join FindMyPast and FamilySearch (free).
