Ever wondered where the historic boundaries were of:

- civil registration districts?
- dioceses?
- poor law unions?
- hundreds?
Quickly find them using the 1851 Jurisdictions Map thanks to FamilySearch.

If you subscribe to Ancestry, then you can also see IHGS County Maps showing not only parish boundaries, but also the dates the parish registers first date from. An extract for the Purbeck area is shown below.
