William Lanyon was a lieutenant in the Royal Navy and twice sailed with Captain James Cook.

William Lanyon joined the navy when he was about 15 years old. His first recorded service was as an Able Seaman on the Orford and then the Mars. He then served on HMS Jason as a midshipman. He moved onto HMS Terrible. In 1772 he joined HMS Adventure one of the companion ships on Cook’s second voyage. In 1773 he was promoted to Master’s Mate.
He was promoted to Lieutenant in 1774 but when he was taken on for Cook’s third voyage he was a Master’s Mate again on HMS Resolution. He was eventually promoted to Second Lieutenant on HMS Discovery in 1779.

He supposedly collected vocabularies of the South Pacific languages which were published in 1979 by Peter Lanyon-Orgill but there is some doubt as to their authenticity.

Between 1790 and 1796 he was in command of the Spider a cutter based at Plymouth. In 1799 he commanded the Kent. In November of that year he captured a French privateer the Four Brothers out of Calais. His last recorded command was of HMS Genereux a prison ship at Plymouth.
By 1814 he was retired and living at St Austell. He was buried there on 26 Mar 1818, the register states he was ‘paralytic’. His wife Jane had been buried at St Austell almost exactly a year earlier on 27 Mar 1817. They had no children.
So where does William fit on the tree?
‘A Genealogical & Heraldic History of the Commoners of Great Britain & Ireland enjoying Territorial Possessions…..’ Vol IV by Burke. has the following entry in the index.
Lanyon, John, 36.
‘Jane b. in November 1765 m. to John Lanyon of Lanyon in Gwinear, grandfather of lieutenant William Lanyon R.N., well known for his various acts of heroism and benevolence in his profession, the last survivor of those gallant officers who accompanied Captain Cook in his voyages. Twice he circumnavigated the globe with that distinguished commander and was with him at the period of his melancholy end.’
The Jane referred to is Jane Willyams and Burke has transposed her date of birth from 1675 to 1765! Vivian’s ‘The Visitations of Cornwall: Comprising the Heralds’ Visitations of 1530, 1573 & 1620‘ prints the family tree of the Willyams family and shows the correct date.

Jane is shown as the daughter of Humphry Willyams of Roseworthy and Dorothy Addington of Devon. Jane was baptised 11 Nov 1675 at Gwinear and married John Lanyon of Lanyon Gwinear.
So who is John Lanyon of Lanyon Gwinear?
Assuming John was a similar age to Jane we are looking for a John born in the 1670s who lived at Lanyon Manor in Gwinear. This would probably be a child of Tobias Lanyon and Susannah Reynolds but they don’t have a child called John and don’t mention a son of that name in their wills. Tobias and Susannah’s son Tobias does have a son called John however he must have been born after 1703 and would be at least twenty-eight years younger than Jane Willyams!
We need to go back and look at the information we have for William Lanyon. There is a note on his Lieutenant’s certificate dated 29 July 1774 which says ‘we have examined Mr. William Lanyon who by certificate appears to be more than 28 years of age and find he has gone to sea more than six years….’ (Captain John Campbell and Captain Abraham North). This implies that William must have been born before 1746.
There is a baptism of William Lanyon son of Mr. John Lanyon and Mary on 2 Apr 1745 at Cuby with Tregony. They have three other children baptised there: Mary 1747, Mary 1752 and John 1755. Of their children, only William survived to adulthood.
There is a marriage between a Mr. John Lanyon and Mrs. Mary Symons at Creed in Cornwall (not far from Cuby with Tregony) on 3 Jan 1742. There is a Mary Symons baptised at Creed in 1715, the daughter of William Symons. We can’t prove it is the same person.
There is a John Lanyon son of Tobias Lanyon, deceased who is apprenticed to Philip Webber of Falmouth, Attorney at Law on 25 Sep 1722 for £52. 10/-


The Jane Lanyon that William married appears to be the daughter of Tobias and Prudence Pawley.
John Lanyon left a will which might have helped clarify this part of the tree but it has been lost!
The Admiralty Record Office wrote to Captian Wingfield D.S.O., R.N., D.G.W. on 17 Feb 1959 and confirmed that:
- William was born in 1745
- Enlisted Sep 1760

- Retired on half pay plus pension from Greenwich Hospital
- Superannuated Commander 1814
- Served on Spider 1790-1795, Kent 1795-1799, Matilda 1800-1804 and Genereux 1805-1806
- Served on HMS Nelson & Resistance under Captain Cook on the voyages of discovery

(William Lanyon of Surrey is Tobias and Prudence’s son William born in 1741.)
We can’t prove that William Lanyon RN is the son of John and Mary Lanyon but it seems the most likely explanation.
To add to the confusion there is a newspaper cutting that further muddies the water by naming Tobias as the person who sailed with Cook!
It’s a valuable lesson on the accuracy of documents!


And finally another article where the dates aren’t quite right, is it any wonder that genealogists make mistakes?
