Lord William Hamilton (1659–1681) Lady Anna Hamilton (1661–1663) Lady Catherine Hamilton (1662–1707), married John Murray, 1st Duke of Atholl Charles Hamilton (1664–1739), later 2nd Earl of Selkirk John Hamilton (1665–1744), later 1st Earl of Ruglen and 3rd Earl of Selkirk George Hamilton (1666–1737), later 1st Earl of Orkney Lady Susan Hamilton, married 1st John Cochrane, 2nd Earl of Dundonald, 2nd John Hay, 3rdd Marquess of Tweeddale Lady Margaret Hamilton (1668–1731), married James Maule, 4th Earl of Panmure Lady Anna Hamilton (b. 1669), who died in infancy. Lord Basil Hamilton (1671–1701) Lord Archibald Hamilton (1673–1754) The Earl of Arran's father died in 1694, and in July 1698 his mother resigned all her titles into the hand of King William, who regranted them to Arran a month later in a charter signed at Het Loo, Netherlands. He was conferred with the titles: Duke of Hamilton, Marquess of Clydesdale, Earl of Arran, Earl of Lanark, Earl of Cambridge, Lord Aven, Polmont, Machansyre, and Innerdale. This regrant of title was presumably because of the loyalty of Arran's parents to the King, as his own affection to the House of Orange was questionable due to his suspected Jacobitism. The Duchess died at Hamilton on 17 October 1716, and is buried there, in the Bent Cemetery. Building works After her marriage the Duchess and her husband set about laying the foundations for what would be, under later Dukes, the largest private residence in the western hemisphere, Hamilton Palace. This was constructed on the site of what was commonly called either the 'Palace' or 'The Orchard', a courtyard style building in the "Low Parks of Hamilton". The Hamiltons had lived in the "Low parks" the more formal area of their estate, in the Clyde valley, since the fourteenth century. In 1684 she commissioned the architect, James Smith to remodel the existing buildings, removing the southern part of the previous courtyard building on the site and increasing the scale of the edifice to form a U-shaped mansion
