William Corris of Pullowon, one of the landed proprietors of the Island in 1791. His name is on the memorial of the principal proprietors of lands in the Isle of Man, dated 31 October 1791 and laid before the Commissioners of Inquiry, standing among the Peel and western signatures. Michael Corris of Peel signed with him. The Corrises were a Peel family of the sea trade. They kept a shipyard close to what is now St German's Cathedral, and they tanned nets and made leather as well, one firm serving several allied trades at once. Their boats were hauled along Atholl Street and down the Gill to be launched on the shore. Caesar Corris was the best known of them as an owner. The Manx Sun described four of his boats in July 1836, of twenty-two tons burden, carvel built, half decked and copper fastened, each carrying nineteen pieces of net of eleven hundred and fifty yards, the nets barked three times before the season opened and every second Saturday afterwards. When the old arrangement by which every man brought his own week's food gave way to a system of shares about 1835, Corris allowed sixteen shillings a week for provisions, two shillings and eightpence a man.

William Cubbon, who argued for a Manx museum before there was one. Writing to The Manx Note Book in the middle 1880s he set out what he thought still wanted doing. There was work of a national character to be accomplished by a society formed on the same lines as the Manx Society: the preservation of national antiquities, the establishment of a museum, and the preservation of the Island's national institutions. The editor added his own hope that the Manx Society would go on adding to its volumes, having funds in hand and much good work still to do, and named the Manorial Rolls of 1511 and 1515 as the next thing wanted. By the next generation he was the man that Manx collectors and emigrants wrote to. At Easter 1913 J. R. Moore, who had gone from Lonan to New Zealand, wrote to Cubbon about the Manx books reaching him from Miss Morrison of Peel, among them J. J. Kneen's Direct Method and Edward Faragher's Aesop's Fables, and about Dr Clague's Reminiscences, in which he said he was greatly disappointed, having expected something racier.

William Hoggatt (1 September 1879 - 4 June 1961) was an English-born landscape painter who moved to the Isle of Man in 1907, married locally at Kirk Rushen, and settled first at Port St Mary and later at Port Erin, which became a hub of the Island's artistic life. Elected to the Royal Institute of Painters in Watercolours in 1925 and later president of the Manx Artists' Society, he exhibited at the Royal Academy and produced a prolific body of oils, watercolours and pastels depicting the Manx countryside, much of it now held by Manx National Heritage.

William IV (1765-1837), King of the United Kingdom and Lord of Mann from 1830 to 1837. His name appears in the Island's records in the form the promulgations took. An Act of Tynwald published at St John's in 1830 is dated in the first year of his Majesty's reign and closes with God save the King, attested by Cornelius Smelt as Lieutenant-Governor. The Manx chronicle records his death as briefly: King William IV died on the 20th June 1837, in the seventh year of his reign. Victoria succeeded him the same day as Queen of Great Britain, Ireland and Man, and issued her proclamation for persons in office to proceed with the execution of their offices on the day after.

William K. Corlett, one of the five founders of the Manx Society at Cleveland, and of the family whose letters are the best record of the emigration. The society was formed in 1851 by James Christian, John Corlett, William K. Corlett, William Cubbon and William Brew, to assist and take care of the poor immigrant from the Isle of Man who came with an empty pocket or in feeble health, and it holds an honoured place among the pioneer bodies of its kind. The Corlett correspondence is the fullest of its kind to survive. Of the private letters written home by the Manx emigrants, those of a William Corlett are reckoned the most complete and the most informative, and they stand beside the diaries of Thomas Kelly of Doolough and Daniel Caley of Jurby as the principal first-hand sources for the settlement. The family kept its name in Cleveland into the twentieth century. Dr William T. Corlett, who lived from 1854 to 1948 and was a grandson of the original immigrant, won an international reputation as a specialist in diseases of the skin.

William Kennish (1799 - 19 March 1862), known as 'The Manx Poet', was a Manx-born Royal Navy carpenter, engineer, inventor and poet who served in the Navy from 1821 to 1841 before teaching school on the Island and later emigrating to the United States in 1849. Surveying in South America, he completed an 1855 report identifying a lock-free canal route across the Isthmus of Panama using the Atrato River, work later publicly honoured at an 1880 New York banquet for canal-builder Ferdinand de Lesseps. He also published poetry celebrating his native Island.

William M'Cowle was a garrison soldier on the Isle of Man who fired the fatal shot at the execution of William Christian (Illiam Dhone) at Hango Hill on 2 January 1663. Of the file of soldiers drawn up for the duty, his was reportedly the only shot that took effect, and he was said to have been rewarded with a grant of land in the north of the Island.

William Montacute, Earl of Salisbury, who took the Isle of Man from the Scots by force and whose son sold it. He had a claim of blood as well as a sword. Aufrica, daughter of Olave II, married Sir Simon de Montacute, and from that marriage the family reckoned itself of the race of the Kings of Man. Camden's account is that what could not be obtained by right, Sir William Montacute won by his sword, mustering a band of English in haste and driving all the Scots out of the Island, and that the war left him deeply in debt. The Wiltshire antiquaries put it that the earl bravely drove the Scots out, recovered the seigniory and crown of the Island from Edward III, and by the King's approbation was called King of Man. The Island's position stayed unsettled for two generations. It was formally included by name in the truce between France and England of 1389, which was signed both by Thomas Randolph, Earl of Moray, as its sovereign in the Scottish interest, and by Montacute as the King of Man whom England recognised. The double signature was thought to have been suggested by the contest continuing unresolved and by the danger from pirates. The sale ended the Montacute lordship. The second Earl, son and heir of the first, is represented in Thomas Walsingham's history, and on that authority in Selden and Dugdale, as having sold the Island and the crown of it to Sir William Scrope for a great sum of money. Scrope was afterwards beheaded for high treason and the Island fell into Henry IV's hands.

William Pitt the Younger (1759-1806), Prime Minister, whose signature is on a Treasury warrant touching the Isle of Man. Peter John Heywood, writing to the Duke of Atholl from the Nunnery at the end of September 1786, passed on what Richard Betham had told him about a commission then issuing for the Island. Betham said the commission was by warrant from the Treasury, signed by Mr Pitt, the Marquis of Graham and another of the Lords Commissioners of that board, but that he did not recollect or believe that the Royal Sign Manual had been affixed to it, and thought that in the circumstances it could not have been. Heywood was at the same time waiting to be served with the Lieutenant-Governor's decree respecting the coins. His administrations carried the ordinary business of the Island through the years after the Revestment, including the continuing negotiation with the Atholl family over what they still held.

William Qualtrough of Kentraugh, who gave evidence against Illiam Dhone and afterwards rose to be Attorney-General. He was one of the four men exempted from the general pardon along with William Christian after the rising of 1651. Unlike Christian he submitted to the lord's mercy, and he was pardoned on 4 February 1663 on condition of bonds and good behaviour. Before that pardon he had deposed against Christian. His deposition was taken at Castle Rushen on 26 November 1662, the last of the seven printed in the Manx Society's edition of the trial, and A. W. Moore thought it was probably taken merely to increase the amount of evidence. Qualtrough said that her Ladyship and the country had been agreed, and that Receiver Christian was looked upon to be their head or chief in the rising at Ronaldsway. The same day the Court of General Gaol Delivery sat, Christian refused to come to abide the law, and the Deputy-Governor demanded the law of the Deemsters. He was on the bench and then in office within a decade. He was made Deemster and reinvested in his estate by the eighth Earl of Derby's own order. By 1672 he was Attorney-General, and he appears in that character in an account of a court held in the interval after Lord Charles's death, when the commissions of all the officers had determined and utterly ceased and their authority with them: Henry Nowell as Deputy-Governor, Richard Stevenson the late Receiver-General as assistant to the courts, Thomas Norris and Edward Christian as Deemsters, Richard Tyldesley as Comptroller and Clerk of the Rolls, and Qualtrough as Attorney-General.

Merged. This man was one of the six jurors who found William Christian, Illiam Dhône, a traitor in 1662. The whole of the record concerning him is the single line of the verdict naming that jury, so the account is now held under one item, The Jury that Convicted Illiam Dhône (1662), rather than divided among six near-empty records. See that item.

William Wilberforce (1759-1833) was a British politician and philanthropist who led the campaign against the transatlantic slave trade. His connection to the Isle of Man relates to the broader political context of the late eighteenth and early nineteenth centuries, during which Manx merchants and ship-owners were involved in various aspects of Atlantic commerce.

William Windham (1750-1810) was a British politician and Secretary at War. His connection to the Isle of Man relates to his involvement in the political affairs concerning the Island's governance during the late eighteenth century.

Willie Craine was a Manx figure.
