Griffiths Valuation, 1847 - 1864

There is an interactive map available now on-line. Mad !!
Parish names may have changed though. You can match the plot number on the map to the list of land tenants.
I was able to find the name of my Great-Great-Grandfather. Land is still in the same family. Of course all tenants to wealthy Landlords at the time.
