The farm still exists today and further information can be found by visiting
http://www.courtyardfarm.co.uk/organic-farming/HISTORY.html. The website states:
"Courtyard Farm covers 750 acres of rolling countryside near the Norfolk Coast. Peddars Way, a Roman road, passes a mile to the west of the farm, and goes through Ringstead village, and Roman remains have been found nearby....In 1784 Courtyard Farm was part of the Hunstanton Estate, owned by the Le Strange Family and it was farmed by their tenants until 1946."
I have just recently contacted Courtyard Farm in the hope that they have some documentation about Thomas I could look at,
Le Strange family
http://www.ls.u-net.com/ documents the history of this ancient family who can be traced back to saxon times. They were mostly known in Shropshire and Norfolk.
"Their long-lived connections with Norfolk dates back to Roland le Strange (Ruallus Extraneus in Latin) who founded these branches around 1100 A.D.. Although the le Strange name died out in Shropshire, the eldest surviving branch remains in Norfolk."
At the time when Thomas was farming the land it would have been under the control of Hamon le Strange and Roland le Strange of Hunstanton.
