John Erskine began building the house at Stirling called 'Mar's Wark', now a ruin under the care of Historic Scotland. The other seat of the family was Alloa Tower. An inventory mentions his silver plate, table linen, and a bed with curtains of red and yellow chequered silk. The posts of the bed were made of walnut and turned (probably carved).HMC Report on the Manuscripts of Earls of Mar and Kellie, vol. 2 (London, 1930), pp. 30–2.
