Using Griffith's Valuation

In this week's guide, professional researcher Fiona Fitzsimmons of the Irish Family History Centre take us through Griffith's Valuation, one of the most important census substitutes in Irish genealogy.

The only complete remaining Irish censuses pre-independence are 1901 and 1911, the rest were almost totally destroyed by fire in 1922. This means that those researching their Irish family history means drawing from a wider range of record sets. Griffith's Valuation is significant in that it can help plug the gap.

Griffith's Valuation is one of the 'hidden treasures' of Irish genealogy, all the more surprising because it's so well known, by reputation.

It's not a single document - Griffith's Valuation includes over 300 books and original maps. It is a detailed record of Irish landholding surveyed from 1846, and published between 1847 and 1864.

Before 2003, no complete set existed, simply because no archive or library had the complete records.

Interpreting the evidence in GV

Column 1 'Number and letters of reference to map.'

This is the reference number for every piece of property in a townland (generally the smallest administrative division of land in Ireland).

Use this number to 'navigate' between the printed books and the maps.

Capital letters A, B, C, D etc. represent parcels of the property divided by soil type.

Lower case italicized letters indicate houses on the land plot.

An italicized lower case 'a' denotes the house of the main householder.

All other italicized letters b, c, d, e, etc. are used to identify habitable houses on the same plot.

Column 2 'Townlands and occupier.'

This has the name of the occupier – the person living on the land, often a tenant.

Column 3 'Immediate Lessors.'

This is the name of the landlord, or sometimes the middleman who sublet a holding.

If land is held 'in fee', then the occupier owns the land.

Occasionally there is no name in column 3, but instead you will find a comment 'Reps. of …', or 'in chancery.'

There were very many reasons why this might happen.

Column 4 'Description of tenement.'

This describes the piece of land set to rent, defined in legal terms as a 'tenement.'

Sometimes the quality of the soil is noted, usually where the land is marginal, and this is stated in italics: 'Land (bog)' or Land '(mountain).'

Columns 5 defines the area of the land in acres, roods and perches.

A rood is about the size of a potato patch.

Columns 6-8 sets out how much income the tenement can produce each year. This yearly income was the basis of the property tax, popularly known as rates.

The bureaucrats that ran the scheme referred to the tax as the Annual Rateable Valuation (A.R.V.).

The A.R.V. was charged in old pounds, shillings and pence - £.s.d.

Column 6 is the yearly tax charged on the land component of the tenement,

Column 7 is the yearly tax charged on all buildings on the tenement.

Column 8 is the sum of tax charged on the land and buildings.

By knowing the A.R.V. – the annual rateable valuation of the house your ancestors lived in, you can determine a lot about their living conditions.

Property is always more expensive in the cities than in rural areas.

A grand Georgian House on one of the fashionable streets in Dublin had an A.R.V. of between £50 and £75.

A country house with an A.R.V. of £40 or over was a mansion house.

In the countryside, including villages any house with an A.R.V. of £5 or more, was built of stone or brick with a slate or tile roof. It would probably have had a minimum of six rooms over two or more levels.

Houses with an A.R.V. of between £2 and £5 were smaller.

The walls were probably built of stone or brick.

Houses on the upper-end of this scale i.e. £4 to £5 might have two levels.

Houses on the lower-end i.e. £2 to £2.5s might have a 'dormer' level, and a thatch roof.

Houses with an A.R.V. of less than £2 were smaller cottages of 2 and 3 rooms.

At the very bottom of the scale you'll find houses taxed at 8s, 10s and 15s. These are the one and two room mud-cabins, with a thatch or turf roof.

Here's an image of a page from Griffith's Valuation:


Townland of Strawhall, parish of Carlow, county Carlow.

Here's how we can interpret this document, for Henry Bruen, the first person listed in Griffith's Valuation for Strawhall:


In the townland of Strawhill Henry Bruen leased three tenements from the Representatives of Benedict Hamilton,

Bruen sub-let a cottage on Lot 1A, to Michael Lalor, who was Bruen's main tenant.

A large mansion-house, presumably Benedict Hamilton's own residence, was left vacant on Lot 1B.

Bruen also left the herd's house vacant on Lot 1C.

Bruen paid £273 in annual tax, of which £3 was for the buildings, and the remainder for land.
