It is not often that I find a useful family history site that I have never
seen before, but today when answering a query about a place in the London
area that used to be in Surrey I came across one which seems likely to be
useful to researchers in many parts of England and Wales
On the GENUKI Surrey page there is a useful link to a Familysearch facility
called 'English Jurisdictions in 1851' at
http://maps.familysearch.org/#?centerLat=51.461836?centerLng=-0.138695?zo...
If you put in the name of a parish it will give you possible options and
then link to a map showing parish boundaries (as on the 'Kain and Oliver'
maps linked from GENUKI parish pages in Glamorgan and Monmouthshire) . A box
with the tab 'jurisdictions' shows you the registration district and diocese
this parish was in. If you use the 'Show Street Map' tab you can see what
modern places are within the old boundaries. If you use the 'Satellite' tab
you can see the nature of the landscape and degree of urbanisation nowadays.
Sadly, for Glamorgan and Monmouthshire the data seems to be very sketchy or
nonexistent, but the parish boundaries are there.
If you are hunting ancestors in much of England this may be useful to see
where the places were that they came from, and what parishes were nearby.
Try it.
