Thanks to British GENES (GEnealogy News and EventS) for letting me know about this useful web site.

The London FamilySearch Centre’s recently upgraded website now includes a series of interactive maps showing the boundaries of a range of key jurisdictions in England as at 1851. The separate layers available include:

  • Counties
  • Civil registration districts
  • Dioceses
  • Poor Law Unions
  • Hundreds

For each layer, you can zoom in to parish level and confirm the relevant jurisdiction. Readers can choose from three different background options:

  1. Map: A simple map
  2. Satellite: Modern arial view
  3. Ordnance Survey: 19th-century Ordnance Survey map

When you find an locality of interest, you can home in on “street view” or follow up a range of options such as compiling a list of parishes within a particular district. Your search can also move on to discover associated material in the Library catalogue and Research Wiki .

This facility is a major boost for anyone with English ancestry. It is particularly helpful if you do not live in the same area as your forebears and are unfamiliar with the record-keeping organisations that operated there in the past.

The facility is available at http://londonfamilyhistory.org/jurisdiction-maps/
