This room was occupied by the 7th Duke of Devonshire during the last years of his life. Holker remained his favourite residence even after he had inherited Chatsworth and all the other Devonshire houses. In comparison to his sons he played little part in political life, though undertaking many public duties.
At Holker, he kept a herd of shorthorn cattle with a worldwide reputation; at a sale in 1878 he sold thirty beasts for a total of £19,922. When his wife Lady Blanche Howard, fourth daughter of the 6th Earl of Carlisle, died in 1840, he was only thirty-two years old; he survived her by fifty-one years and did not marry again. He was a scholarly man with a retiring nature but was devoted to his children and grandchildren, whom he saw as often as possible.
