St Mirin was an Irish monk, a disciple of St Comgall, from the monastery of Bangor in Co Down, and contemporary of St Columba. He laboured in the area of Paisley, Glasgow and founded a monastery there. There may have already been a Christian settlement there since Roman times – just as there may have been at Old Kilpatrick (Church of St Patrick). He also founded a monastery on the island of Great Cumbrae in the mouth of the Clyde and planted another on Inchmurrin on Lough Lomond.
