Oliver William Twisleton-Wykeham-Fiennes (17 May 1926 – 8 June 2011) was Dean of Lincoln in the latter part of the 20th century.[1]
He was born on 17 May 1926 into a noble family, the youngest of three sons of Ivo Twisleton-Wykeham-Fiennes, 20th Baron Saye and Sele.[2] He was educated at Eton College and won the Sword of Honour as best overall cadet at the Royal Military College, Sandhurst. He was commissioned into the Rifle Brigade on 1 September 1945 as a second lieutenant, but saw no fighting as the Second World War ended soon afterwards.[3] He subsequently went up to New College, Oxford.
Ordained in 1954, after a spell as a curate at St Mary Magdalene, New Milton, he became chaplain of Clifton College in 1958. Following this he was rector of Lambeth before his elevation to the deanery.[4] Described by Trevor Beeson as “the last aristocrat to make his mark on the church",[5] in retirement he lived near his old Cathedral in Lincoln until his death in June 2011.
