Petty’s Fieldbooks
Archived: 14 October 2026
In 1656, Cromwellian Ireland was being reorganised through Sir William Petty’s Down Survey, which recorded land, boundaries and value to distribute forfeited estates among soldiers and adventurers. Field books enabled officials to assess claims while reserving specified public and ecclesiastical lands. This administrative project underpinned confiscation and the uneven, coercive transplantation of Catholic landholders to Connacht and Clare, affecting rural society beyond formal removals. Henry Cromwell sought firmer Protestant civil government amid army and religious divisions, while war with Spain heightened security concerns. Catholic communities endured repression; Quakers faced persecution. Ussher’s death, Ware’s Patrick edition, and Molyneux’s birth reflected continuity.
