William Lanyon was born in Tregony, Cornwall in 1747. He joined the Royal Navy when he was about 18 and served as an A.B. and midshipman on HMS Terrible. In 1772, possibly through Cornish connections, he joined HMS Adventure, Cook's companion vessel on the second voyage. From September 1772, he served as a midshipman but following the deaths at Grass Cove in December 1773 he became a master's mate.
Lanyon was taken on again for the third voyage, again as master's mate, on the Resolution. Following Clerke's death in August 1779, Lanyon was promoted to second lieutenant on the Discovery. Lanyon kept a log during the voyage. He is also supposed to have collected vocabularies of Pacific languages, which were assembled and published as "Captain Cook's South Sea Island Vocabularies" by Peter Lanyon-Orgill in 1979. Their authenticity has, however, been questioned by Paul Geraghty and others.
Lanyon's subsequent record is sketchy. He is listed as commanding HMS Genereux, a prison ship, at Plymouth in 1805. In 1814, he was listed as a superannuated commander. He retired to St. Austell, Cornwall, a sick man, and died in March 1818 leaving a will (FRC 11/1604).

Isaac George Manley sailed on the Endeavour as master's mate until 04 February 1771 when he was made a midshipman. After sailing with Cook, he was promoted to lieutenant in 1777, commander in 1782, and captain in 1790. Later in 1809 he became a rear admiral in 1809, a vice admiral in 1814, and an admiral in 1830. Manley was aboard the Fairy in April 1782 during Rodney's victory at the Battle of the Saintes in the West Indies. He was later in command of the Apollo (38 guns) in June 1796 when it captured the Legere, a French corvette of 22 guns off the Isles of Scilly. Manley had left the Apollo before it was wrecked in 1799.
The Manley family owned Manley Hall at Erbistock, near Wrexham and Isaac George was probably born there in 1756. An earlier Isaac Manley, possibly Isaac George's grandfather, had been Postmaster General in Dublin at the beginning of the eighteenth century and had known Jonathan Swift. Isaac George Manley acquired Brazier's Park outside Checkendon in Oxfordshire and he died there on 29 July 1837, leaving a will (FRC 11/1886). He had married Frances Pole and together they had two children, Ann Frances and John Shaw Manley, who followed his father into the navy. Manley received a Doctor of Civil Law from Oxford University in 1814. Manley Island, an islet off the north Queensland coast is named for him.
