TheGenealogist has added to its ever-growing Landowner and Occupier records by releasing more than 170,000 individual heads of households and property owners in Northamptonshire.

Covering 345 parishes surveyed between 1910-1915 for the Inland Revenue Valuation Office, these records are a fantastic tool for family, house or social historians to use.

The project has seen years of collaboration between The National Archives and TheGenealogist in conserving and digitising these records. Comprising the IR 58 Field Books and accompanying IR 121 to IR 135 Ordnance Survey maps, they join the millions of records in TheGenealogist’s powerful research tool, Map Explorer™.

TheGenealogist now has over 2.4 Million records from The Lloyd George Domesday Survey. The coverage is rapidly expanding and currently includes all the boroughs of Greater London plus Bedfordshire, Berkshire, Buckinghamshire, Hertfordshire, Oxfordshire, and Middlesex, as well as the newly added parishes from Northamptonshire*.
