On Friday morning, 30-year-old Matthew Bradford was found dead on the 2000-acre Carnell Estate in Ayrshire by the household's farmer.
Deborah Findlay, 51, whose husband's family has owned the estate for centuries, said she was out of the house when the discovery was made.
"I only found out on Friday afternoon when I heard from one of our employees. Obviously I was very shocked. My thoughts are with his family, because these things are very very upsetting for everybody concerned," she said.
Police are treating the death of Mr Bradford, from Hurlford, Ayrshire, as unexplained.
