Fr.William Brennan was born in London in 1937. He was educated at St Edmund's College Ware and was ordained in London for the Archdiocese of Westminster in 1962. After serving the people of London for 20 years he came to the Archdiocese of St Andrews and Edinburgh in 1982 where he was posted to St John the Evangelist in Portobello as assistant priest where he remained until 1985.

From 1985 until 1988 Fr Brennan was assistant Priest at St Francis Xaviour's Falkirk. He then came here to St Patrick's Kilsyth in 1988 as assistant Priest to Canon Karl Krugger and he was to witness a turbulent time in the history of St Patrick's which co-incided with his period here.

Firstly his Parish Priest Canon Krugger was to die suddenly and unexpectedly on 24th May 1989 shortly after Fr Brennan's arrival in the Parish. After Canon Kruggers death Fr Ben Doonan was appointed as the new Parish Priest in St Patrick's and he too died suddenly and unexpectedly just afew weeks after Fr Brennan's departure. Fr Brennan was replaced as assistant priest by Fr Steve Gilhooley in 1990.

Fr Brennan went onto serve a number of other Parishes notably The Immaculate Conception in Kelso starting in 1990 after he left Kilsyth. We think that he also served in another parish in Fife for a short while before being admitted to hospital in Dunfermline where he died on 20th August 2003. May he rest in peace.
