John Callaghan was born in Kilsyth in 1938. He was educated at Blairs junior Seminary in Aberdeen and at The Scots College at Valladolid, Spain. He was ordained there in Valladolid in 1962.

His first posting was to St Patrick's Edinburgh where he served between 1962 and 1967. He was then transferred for 2 years between 1967 and 1969 to St Margaret of Scotland, Raploch in Stirling. After a period of 2 years where Fr Callaghan was c/o the Diocesan Office, he went on missionary work abroad to Bauchi in Northern Nigeria which has long been associated with the Archdiocese of St Andrew's & Edinburgh. On his return to Scotland Fr Callaghan went to Our Lady and St Ninian's Bannockburn from 1975 to 1979.

In 1979 Fr Callaghan was transfered to Our Lady & St Andrew's in Galashields in the Scottish borders and then to St Margaret's at South Queensferry from 1981 to 1987.

The final Parish for which we have a record of Fr Callaghan is back to Bannockburn in 1987. Fr Callaghan now lives in retirement in Stirling.
