If you have an older house then the deeds can give you a great insight as to who has owned your property. It may be that your solicitor still has the deeds and you could examine them. Worth a check when you can.

Moccas Estate Sale 1919 Properties in Dorstone, Peterchurch and Bredwardine
List of properties presumably, sold by Powell family in 1940. Possibly to Lord Brocket of Kinnersley Castle. Lord Brocket looks to be a interesting character, if we can believe Wikipedia. As he appears to have connections with Nazi Germany and attended Hitler’s 50th birthday party!!! From National Library of Wales
