The manager of Lord Caledon's private country estate in Northern Ireland has been killed while working on his land.
Father-of-two Keith Willis is believed to have been hit by a tree which was being cut down.
Close friend Jim Hamilton said: "He was Lord Caledon's right hand man. Everyone is just devastated."
Health and safety officials were called in to investigate the accident on the 5,000 acre estate on the outskirts of the Tyrone village of Caledon.
Lord Caledon, the Queen's Lord Lieutenant for Armagh, also owns a house in Oxfordshire and another estate in Hertfordshire.
He remarried three years ago at a private wedding ceremony in Chelsea.
Mr Willis, married with two daughters, worked on the estate since leaving school. He lived in Caledon and was heavily involved in the village regeneration plans.
His brother Cyril, a police officer, was killed more than 20 years ago when his patrol car was blown up by an IRA bomb in near the village of Killylea, Co Armagh.
Mr Hamilton, an Ulster Unionist councillor from Aughnacloy, Co Tyrone. said the local community was in shock.
He said: "Keith Willis was so much part of village life. He was involved in everything - everything from organising the children's Christmas parties and street lights to helping out with the regeneration of the place."
