Description:
Census data that was submitted based on civil parish is organized here by civil parish. Otherwise, it is organized by District Electoral Division, which were defined areas of townlands. Be sure to check both indexes to look for your townland. A few townlands are duplicated on both the civil parish and DED organization.
