William Francis Brinsley Le Poer Trench, 8th Earl of Clancarty, 7th Marquess of Heusden (18 September 1911 – 18 May 1995), was a prominent ufologist.
Clancarty was an honorary life member of the now defunct Ancient Astronauts Society which supported the ideas put forward by Erich von Däniken in his 1968 book Chariots of the Gods?.
In 1975 he succeeded to the earldom on the death of his half-brother, Greville Trench, 7th Earl of Clancarty, giving him a seat in the British Parliament.
Trench also believed that the lost continent of Atlantis actually once existed and that these tunnels were probably constructed all over the world by the Atlanteans, for various purposes.
Trench believed that there was no actual North Pole, but instead a large area with a warm sea dipping gradually into the interior of the Earth.
[2] According to Trench in his book The Sky People, Adam and Eve, Noah and many of the other characters from the Bible originally lived on Mars.
He further claimed that the north polar ice cap melted on Mars, and this caused the descendants of Adam and Eve to move to Earth.
[4][5] Trench also claimed to know a former U.S. test pilot who said he was one of six persons present at a meeting between President Eisenhower and a group of aliens, which allegedly took place at Edwards Air Force Base on 4 April 1954.
