Interactive Map: 1850 Irish Census, by Parish

Click Here To See The Map

This interactive map shows where people of specific surnames lived in Ireland in the 19th century, according to parish records.

I scraped a static dataset from the Irish Times website, and built a much more interesting way to view the same information, with additional insights provided by clustering of semi-opaque colored markers.

The dataset has 4 pieces of information: latitude, longitude, name of parish and number of family surnames in that parish, E.G.,

[52.23462, -9.46187, ‘Castleisland’, 1],
[52.143351, -10.26865, ‘Dingle’, 1],
[52.476298, -9.535789, ‘Galey’, 1],
[52.561638, -9.615955, ‘Kilconly’, 1],
[52.09152, -9.25196, ‘Kilcummin’, 9]
