Historical Maps of County Clare
Clare GenMaps (New!)
- mapping
surnames, monuments and places in County Clare with Bing, Open Street Map, ESRI and the 1842 Ordnance Survey maps of Clare

Clare GenMaps
The above map shows surname distribution for 'Barry' in the 1901 Census

Clare GenMaps utilise the ESRI ArcGIS API for FLEX, allowing ESRI, Bing and Open Street Maps to be overlaid with historical maps of Clare from 1842. This new system, developed for us by Rainer Kosbi, allows us to represent surname distribution from the 1820s Tithes, 1855 Griffiiths and 1901 Census datasets as interactive heatmaps linked to the extensive data on our website. The maps are also linked to the thousands of pages on this website dealing with the archaeology, history and administrative divisions of County Clare.

About this project

The Clare Genmaps

Clare GMaps 



The Clare GMaps were based on the Google Map system.
Google discontinued their Flash API on September 2nd 2014, so our GMaps system is no longer functional. Our Clare Genmaps system, based on ESRI’s Flash API, replicates (and indeed improves upon) the older GMaps system.

The Clare Townland Fieldname Survey
In 2010 the Clare Placenames Committee, with the support of highly capable and trained surveyors, trained interested parties throughout the county in the collection and recording of fieldnames; organised a media campaign to raise the awareness of such; and continue to collect new information in eighteen townlands.... As a final aim, the Committee aspires to the digitisation of research on placenames in the county previously undertaken, but which was not made available in digital format.
