Dowlish Wake home of the family of John Hanning Speke who took part in three expeditions to Central Africa from 1854-1862, the last two in search of the source of the Nile. He discovered Lake Victoria and maintained that it was the source of the White Nile. On his third expedition, Speke identified Ripon Falls, the outlet of Lake Victoria, as the source of the Nile; this was confirmed by Henry Morton Stanley in a later expedition. Speke was killed in Neston Park in Wiltshire by his own gun while hunting with his cousin on 18 September 1864; Dr David Livingstone and
John Hanning Speke tried to remove it with a knife. Unable to rent the larger vessel from the Arab, Speke returned. The pair were unable to explore Lake Tanganyika properly and they initially misunderstood that a river flowed out of it from the north side. A few weeks later Sidi Mubarak Bombay confirmed via locals that the river flowed into the lake; however, since neither man actually saw this river, this remained a source of speculation. They had also heard of a second lake to the north-east, and in May 1858, they decided to explore it on the way back to the coast.
