The 10th Viscount Strathallan had made the estate's Dower house ''Machany House'' his primary residence by the time he died in 1893. During the early 1900s Strathallan Castle had been leased to Graeme Whitelaw M.P.
Following Whitelaw's departure from the district, in 1910 William Drummond, 11th Viscount Strathallan (who had also succeeded a distant cousin as ''Earl of Perth'' in 1902) sold the ancestral Strathmore Estates at Strathallan, Tullibardine, and Machany ''(then comprising 7,322 acres)'' to industrialist Sir James Roberts, 1st Baronet.<ref name="StrathallanHistory">“The History.” Strathallan Castle, accessed 13 Nov 2025. http://www.strathallancastle.co.uk/the-history/</ref><ref name="PerthshireAdvertiser10Aug1910_p7">“Sale of Perthshire Estates.” The Perthshire Advertiser, etc., 10 Aug 1910, p. 7.
