Sir William Cunningham of Kilmaurs had married Margaret Denniston, sole heir to Sir Robert Denniston in 1405. The dowry included the baronies of Denniston and Finlaystone in Renfrewshire, the lands of Kilmaronock in Dumbartonshire, and the barony of Glencairn in Dumfrieshire. In 1616, many parcels of land belonging to the Barony of Kilmaurs were disposed of, together with Kilmaurs place and other possessions. In 1520, Lambrochton was acquired by Hugh, first Earl of Eglintoun (see Townhead of Lambroughton). Paterson (1866) states that Lambruchton was one of the lands inherited by Alexander Cuninghame of Corshill in May 1546, held by right of Royal Charter. In 1632, Alexander Conyngham had Lambroughton and Crumshaw Mills; in 1640, Johne Conyngham held part of the lands of Langmure, probably including Lambroughton, at a valuation of £200 a year, the rest being held by Stewart Fergushill at £66, 12 shillings and 10 pence. In 1667, Mr. John Cuninghame of Lambrughton (later Sir John) was one of the thirteen Commissioners of Supply for Ayrshire. The main purpose of the commissioners was to organise the collection, in an effective manner, of taxes. Their significance was that they held their power directly from royal authority and not as a feudal right. They later took on the role of organising education and the control of roads, bridges and ferries. They were replaced in 1890 by the County Councils, but survived with a few vestigial functions until 1929. Sir John Cunninghame of Lambroughton was the patron of Dreghorn and Kilmaurs kirks in 1670. He was an advocate, one of the most distinguished lawyers of his day, and obtained the sanction of parliament to use vacant stipends for the purpose of repairing churches and manses in these parishes. He already possessed the lands of Lambruchton, before acquiring in 1683 the barony of Caprington from John, Earl of Glencairn. John Cuninghame of Broomhill, Lambructon, and Caprington was created a baronet on 21 September 1669 to him and his male heirs only. and died 1684, succeeded by his son, Sir William, who is titled 'of Caprington' only. The history of the family is that of the Cunninghame's of Caprington from this point on. In 1667 John Cuninghame of Lambrochton (sic) sold Brounehill to William Cuninghame. The property had been held by the Cuninghame of Lagland, cadets of the Earls of Glencairn. In 1675, Sir John Cunninghame Bart., conveyed to Robert Cunningham, druggist / apothecary,
