In 1986 John Twisleton was called from his Doncaster parish to serve the Diocese of Guyana in the West Indies as a Theological College Principal. Whilst training as a missionary at USPG’s College of Ascension in Selly Oak he met his wife to be, Anne Cockerham, a widow with two sons, David (11) and John (9). Between 1987 and 1990 John helped train six men from Guyana’s Amerindian community as priests at the Alan Knight Training Centre, Yupukari. He was joined by Anne. They were married in 1988 by an indigenous priest at St. Mary’s Church in Yupukari. Anne helped Fr. Allan Buik and John with the running of the seminary which was based in the savannah area of the Rupununi near to Guyana’s border with Brazil. After the priests were ordained in 1990 John, Anne and John junior returned to the UK for the birth of their son, James. Since 1990 John and the family have retained links with the Diocese visiting the priests he trained and their congregations in 1995, 2000, 2007, 2011, 2014, 2015 and 2016.
