Sir Garbutt Knott lived at Courtlands in Exmouth, Devon until his death in 1949. He had married Margaret Annie Anderson in 1925 but there were no children from the marriage. Most of his estate was left to the Trust set up by his father, Samares Investments.(http://www.knott-trust.co.uk/knott-family-history)
Так что Trust и является владельцем имения.
