His son Robert was one of the most learned men of his time, and wrote an elaborate commentary on the Ephesians, of which Dr James Walker says:—"It is a work of stupendous size and stupendous learning. The Greek and Latin fathers, the writers of the dark ages, the Protestant and Romish theologians of his own time, are all at hand to render aid or to receive replies." He was born in Glasgow, brought up at Trochrague, educated at Ayr, and took his degree in Edinburgh. He then went to France, where he was appointed Professor of Divinity at Saumur. King James I. having, in 1615, heard of his fame, appointed him Principal of Glasgow University, and afterwards of Edinburgh University. Finding him, however, more staunchly Presbyterian than his father, the king caused him to be deprived of his office. He next became minister of Paisley, but a riot having been instigated against him, he demitted his charge, and retired to Trochrague. In declining health he went to Edinburgh in search of medical advice, where he died in 1627. In his will, he left twenty pounds "to help to buy ane bell to the kirk of Daylie, and twenty merks, including thairin the ten merks alreaddy promeist, to the bigging of the brig of Gimme." His grandson, also called Robert, was a staunch Covenanter, like most of the Carrick lairds, and was thrown into prison for refusing the Test oath, only obtaining his liberty on payment of a fine of a thousand merks for church irregularities, and giving a bond and caution for ^2000 sterling, to live regularly and orderly in future.
