In 1645, Johne McMillane of Brockloch is named among those who petitioned for the erection of a place of worship at Carsefearne (Carsphairn) and the following is an extract of the act passed in the Scottish Parliament :— “Anent supplications Givine in to the estates of Parliament Quhairof the tennor followes UNTO your Lords the honorable estates of Parliament Humbly means and shows I your servitor Alexander Gordon of Knockegray for my self and as commissioner and in name of the remaining heritors of the lands underwritten that where we be heritors’ tennants of be fourscore merk land following—viz.

On 11th February 1659, Robert, son of Sir John Grierson of Lag had retour of Brockloch, Longfurd, etc. and again, on 29th April 1669, Robert, son of Sir Robert Grierson, had retour of the above, with Drumjoan (Drumjohn). During those “killing times“ many Covenanters suffered for their faith, including a number of MacMillans. Two of them, Alexander* and James, were taken after the skirmish at Pentland in 1666 and are among the martyrs belonging to Ayr. Four years earlier, Johne McMillane of Brockloch was fined £360 for non-conformity to Prelacy. This accounts for the appearance of the Griersons and their temporary possession of his land. On 7th November 1663, ‘Bessie (Betrag), dochter to William Aird’ and wife of Johne McMillane of Brockloch) had sasine as portioner of half of her husband’s land.
