Census House Numbers and Maps

Hi all,

In relation to the Census, there's an entry for each household saying 'House No. 1' etc.

Is there a corresponding map that helps you identify where exactly/approximately the house is located?

Thanks in advance,

  • The numbers given on the census are enumerator references, and so dont usually correspond to any street number or official addresses. The numbers were simply the order the enumerator visited each property to collect the census forms, the sequence is often different between the 1901 and 1911 census.

    The one exception to this is that some of the references correspond to building numbers for some streets in cities and larger towns, particularly on the 1911 census forms (rural areas do not use street numbers).

    I dont believe the enumerators created any maps showing the sequence they used.

    For many areas you can establish a more detailed location for a property using the Cancelled Land Books, aka Revision Books. These are a continuation from Griffith's Valuation and in a similar format, and keep the same plot numbers forward up to the 1900s. The books are held by the Valuation Office in Dublin city, they also have later maps, similar to those used for the original Valuation showing where each property was located. These records are not currently available online.

  • Hi Shane, 

    Thanks a million for that. Yeah, I know houses in rural areas didn’t have numbers, and still don’t! But I thought there must have been some reason for the enumerator to allocate numbers. 

    But, I will check out the Cancelled Land Books like you suggested.

    Thanks again,

  • The Valuation books for some counties, including Co, Donegal, have been digitized and are available on computers in the Valuation office on Lower Abbey St. The books are arranged by Electoral District (DED on the census), and for rural areas the books are arranged by Civil parish and townland.  Electoral district boundaries sometimes altered with population changes, so you may have to check adjacent districts. A new book was started every 10 to 20 years.

    If the household you are looking into had connections to the same area going back some time and lived in the same townland back as far as Griffith's Valuation you may be able to use the plot references on the corresponding maps to work out a matching site.
