“Ireland, 1850: Dee Households by Parish”

Number of Households Per Parish:

  • Green < 5
  • Yellow 5 - 10
  • Red > 10

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, which was served up as a static image.

I wanted a much more interesting way to view the same information, so I built one with additional insight provided by clustering of semi-opaque colored markers.

The static dataset from the Irish Times has 4 pieces of information: latitude, longitude, name of parish and number of family surnames in that parish.

Built with PHP, Leaflet & JavaScript.
