"The church of Kirkoswald was dedicated to St. Oswald, one of the kings of the Heptarchy. The festival day of this saint was the fifth of August, and from time immemorial a fair has been held at Kirkoswald on that day. The church is situated within the barony of Turnberry, and was anciently called 'Ecclesia Sancti Oswaldi de Turnberry'. It was granted to the monks of Paisley by Duncan, Earl of Carrick. At a later period the church of Kirkoswald was transferred to the monastery of Crossraguel. The old church stood in a low situation, and was surrounded by the burying ground. It was here, in 1562, that Abbot Kennedy preached those sermons against the Reformation, which led to the famous debate between John Knox and him."
"This church was superseded by a new one, in 1777, built a little to the south of the old structure. The Ailsa family have a burial vault at the church, but it has never been used. In the graveyard a tombstone has been erected in memory of Douglas Graham, who, in the days of Burns, was a tenant farmer in the farm of Shanter, and was the hero of the poet's masterly effusion, 'Tam 0' Shanter'. There is also a tombstone belonging to the family of Brown, from whom the poet's mother was descended, and one to the memory of Hugh Rodger, who was Burns's teacher of Mathematics when he attended Kirkoswald School."
