Farren was Ireland's youngest bishop when appointed in 1939 and during the Second World War he was appointed "ordinary" of the American forces in Ireland, a service recognised by the award of the
United States Medal of Freedom. He participated in the
Vatican Council in
Rome (1962–65). He was bishop during 'the Troubles' and during 'Bloody Sunday'. During his time as bishop he campaigned for a university in
Derry. He took an active interest with his
Church of Ireland counterpart,
Cuthbert Peacocke, in seeking to restore peace among the communities in
Derry, and he engaged with nationalist and civil rights activists
Eddie McAteer and
John Hume. A book about Dr. Farren has been written by Rev. Bernard Canning of the
Roman Catholic Diocese of Paisley in Scotland. An obituary recalled that he became bishop at a time of rapid expansion and that he "opened 25 new schools, 23 new post-primary schools and many more primary schools." He served as
Bishop of Derry until his 80th birthday in 1973. and then as apostolic administrator until the appointment of
Edward Daly as his successor in 1974. Farren died on 7 May 1980, aged 87, having spent his retirement in his native Buncrana. His remains are interred to the right of the main entrance of
St Eugene's Cathedral, Derry. Next to his remains lie the remains of his successor, Dr. Edward Daly. ==See also==
