The Duke purchased the Manor of Pemberton (near Wigan) in 1758, the Manor of Hindley in 1765, and the Manor of Cadishead in 1776. Upon his death in 1803 he was succeeded by George Leveson-Gower, 1st Duke of Sutherland. In 1833 the estate was inherited by Gower's son, Francis Leveson-Gower who changed his surname to Egerton, and in 1846 became the Earl of Ellesmere. In 1836 he purchased the Manor of Tyldesley. He is recorded as saying that he found Worsley to be "a God-forsaken place, full of drunken, rude people with deplorable morals".
