The document describes a book of maps from 1824 depicting the Earl of Derby's landed estate in Ballykisteen, Limerick-Junction, Ireland. The estate consisted of 20 maps showing the fields, roads, buildings and tenants of the various townlands. Each field number, acreage and land use. A table provided details of tenant farmers' names and fields. The estate was later owned by the O'Brien O'Connor family in 1873 before being sold. The maps provide a record of landed estates and tenant farming in Ireland during this time period.
