After the Reformation it was proposed by the General Assembly, in 1581, that the Presbytery should be erected as the Presbytery of Crieff. The Assembly, on 8th April, 1593, "ordaines the Presbyterie of Dumblane to be transportit to Ochtirardour, and ordainis the Presbyteries of Stirling and Perth to establishe the said Presbyterie in Auchtirardour upon Thursday come xv. days," being 19th April, 1593. It was changed to Muthill prior to 18th January, 1633, but Auchterarder was resumed before 1638. At the Reformation the parish of Auchterarder was supplied by David Murye, reader, in 1567. The first Protestant minister in Auchterarder was John Hamyll. He was previously vicar of Dunning, having succeeded there to his uncle, Sir John Hamyll, who from his title was likely vicar of Dunning in the old church and conformed to the new opinions. John Hamyll was presented by King James VI. to the Vicarage of Auchterarder on 28th June, 1568, and to the Vicarage of Aberuthven on 1st March, 1582. He had also charge of Kinkell and Dunning. John Graham was minister of Auchterarder in 1636. He was a member of the General Assembly at Glasgow, in 1638, at which the famous James, Marquis of Montrose, was representative elder from the Presbytery of Auchterarder, he being then on the Covenanting side. Mr Graham was deposed by the Commission of the Assembly on 27th November, 1644, for speaking once to the Marquis of Montrose.[12] The sentence was taken off by the Assembly, 8th February, 1645; but he was again deposed by the Assembly, 6th July, 1649. His prelatic predilections were attributed to his wife being a descendant of John Hamilton, the last Catholic Archbishop of St. Andrews. James Drummond, son of the Rev. James Drummond, minister of Fowlis, and a near relative of the Earl of Perth, was successively incumbent of Auchterarder and of Muthill. He was consecrated Bishop of Brechin on Christmas Day, 1684, in the Chapel Royal of Holyrood. He is reported to have been a man of strict Protestant principles, and a decided opponent of King James' interference with the Church, though he, like most of his brethren, was a keen supporter of hereditary monarchy, and took a decided part with King James when the most of his courtiers deserted him. Bishop Drummond was deprived of his bishopric at the Revolution, having preached at Brechin for the last time on Sunday, 18th April, 1688.[13]
