Lloyd Kenyon (1947–2019)

By Shaun Haddock | August 24, 2019

Lloyd Kenyon and his wife Sally will be well known to members who attend IOS and IDS events, and together they planted a diverse collection of oaks at the Gredington Estate. which the IOS was privileged to visit in 2015.

Everyone who knew him will thus be as shocked and saddened as I was to learn of Lloyd’s recent death after a short illness.

Lloyd’s funeral will take place near his home on Friday, August 30, at St. Chad’s Church, Hanmer, Whitchurch, UK. I know that all will join with me in expressing our deepest sympathies to Sally and their family.
