Major explorations after the Age of Discovery to locate the source of the River Nile. Expeditions by Burton and Speke (1857–1858) and Speke and Grant (1863) located Lake Tanganyika and Lake Victoria. It was eventually proved to be the latter from which the Nile flowed. Explorers were also active in other parts of the continent. Southern Morocco, the Sahara and the Sudan were traversed in many directions between 1860 and 1875 by Georg Schweinfurth and Gustav Nachtigal. These travellers not only added considerably to geographical knowledge, but obtained invaluable information concerning the people, languages and natural history of the countries in which they sojourned.

Manor of Orleigh assumed the name Lee, as he was required to do under his uncle's will, and purchased as his residence Dillington Manor near Ilminster in Somerset.

Speke had seven children, all but one daughter having been born at Orleigh, including his eldest son the famous explorer and discoverer of the source of the River Nile, John Hanning Speke (1827–1864). The Speke family gave up their tenancy of Orleigh in 1845 and Mr Lee next let the house to Col. Bayly from 1845 to 1856 and then to Capt.
