In 1820 James Kennedy, who had been ministering around Loch Tay, visited the Strathardle and Blackwater valleys. A time of revival began in both glens, producing 'the most remarkable change in the life and character of many.' Kennedy said that the men of Strathardle were mostly moved by the terrors of the law, in contrast to the people he preached to in Breadalbane (Loch Tay), who showed themselves most accessible to the sweeter influences of the Gospel - the love of Jesus Christ.
Some travelled 20 miles to hear him speak and followed him to every place he preached between Moulin and the head of Glenisla, Glenshee, Blackwater, Blairgowrie, Kirkmichael and Glenbriarachan.
