The Knights of St Columba is a fraternal service order affiliated with the Catholic Church in Scotland, in England and Wales,[1] and, through their Province of Liverpool, in the Isle of Man.

[6] In 2012, the organisation made public calls, reported in the news, for a street in York to be named after local Elizabethan era Catholic saint Margaret Clitherow, who had been canonized by Pope Paul VI as one of the Forty Martyrs of England and Wales.

[7] In 2018, The Times of London reported that the Knights, after meticulous research, had made a ruling that Alice Nutter, a Lancashire noblewoman and Recusant who was convicted and executed for attending a witches' coven on Good Friday, 1612, was in reality a Catholic martyr.

[8] Since 2020, the Knights' Council 1 at the University of Glasgow has been promoting Fr Alexander Cameron (1701-1746) by distributing holy cards with a prayer for his Canonization as a Saint and a Martyr by the Catholic Church.

Cameron (Scottish Gaelic: Maighstir Sandaidh), was an outlawed Jesuit "heather priest" working among Clan Chisholm and Clan Fraser of Lovat in Strathglass, the Aird, and Glen Cannich during the Penal Laws and Jacobite Army military chaplain, who died after the Battle of Culloden aboard a Royal Navy prison hulk anchored in the River Thames.
