The family seats are [[Chatsworth House]], [[Bolton Abbey]] in [[Yorkshire]], and [[Lismore Castle]] in [[County Waterford]], in the [[Republic of Ireland]]. [[Compton Place]] in [[Eastbourne]] belongs to the family (which developed Eastbourne as a seaside resort in the 19th century) but is let. In 1908 [[Holker Hall]], then in [[Lancashire]], now in [[Cumbria]], was left to a junior branch of the family. The family previously owned [[Londesborough Hall]], [[Yorkshire]]; [[Hardwick Hall]], [[Derbyshire]]; [[Chiswick House]], [[Middlesex]]; and two [[London]] mansions on [[Piccadilly]]: [[Devonshire House]] and [[Burlington House]]. In 1907 the Duke owned 192,322 acres across the [[British Isles]], principally in [[Derbyshire]], [[Yorkshire]], [[County Cork]] and [[County Waterford]].<ref>H.
