About Thomas Dunckerley

Lived 1724 – 1795 (aged 71).

Thomas Dunckerley (23 October 1724 – 19 November 1795) was a prominent freemason, being appointed Provincial Grand Master of several provinces, promoting Royal Arch masonry, introducing Mark Masonry to England, and instituting a national body for Templar masonry. This was made possible by an annuity of £100, rising to £800, which he obtained from King George III by claiming to be his father's illegitimate half brother.

Early career In 1735, Dunckerley was articled to William Simpson, a barber and peruke maker of St Martin-in-the-Fields, Westminster, but ran away after just two years to join the navy. He is recorded from 14 April to 4 August 1742 as an able seaman on the muster book of . On 6 January 1745, the minutes of Trinity House at Deptford record that 'Mr Thomas Dunckerley being Examin'd & found Qualify'd to be a School Master in her Majesty's Navy & having produc'd a certificate (as usual) of his Sobriety & good Affection to his Majesty, he was certify'd accordingly'. He is first mentioned in Admiralty records on 19 February 1744, when, not quite twenty years of age, he was appointed schoolmaster on a seventy gun ship called . In 1746, he was appointed Gunner on a sloop, a term equivalent to Chief Gunnery Officer. He proceeded to posts as Gunner on larger ships, including the 90-gun (ex-Triumph). From 1757 to 1761 he served on as both Gunner and Schoolmaster. On this ship, he saw service at the Siege of Quebec. After service on HMS Prince, he was superannuated in 1764.

Dunckerley's claim of royal paternity was not universally accepted in his lifetime. On his death at least one contemporary cast doubt on his illegitimacy. Recent studies also claim to refute his own version of his parentage, although Arthur Edward Waite certainly accepted it, perhaps based on his resemblance to George III in his portrait.

Dunckerley as Freemason Dunckerley was initiated into Freemasonry at Lodge No 31, at the Three Tuns in Portsmouth, in January 1754. In 1760, he obtained a warrant for a lodge aboard HMS Vanguard, which he took to form London Lodge (now No. 108) in 1768. After leaving Vanguard, he obtained a warrant for a lodge on HMS Prince, which he later transferred to HMS Guadeloupe. This later became the Somerset House Lodge, meeting at the Turk's Head in Soho. With the Vanguard warrant, he obtained a roving commission from the Premier Grand Lodge of England to inspect the state of the craft wherever he went, including "to regulate Masonic affairs in the newly acquired Canadian provinces." Under this authority, as Acting Grand Master of all Warranted Lodges in Quebec he installed the first Provincial Grand Master of Canada, Col. Simon Frasier, in Quebec in 1760.

In 1767, he was appointed Provincial Grand Master of Hampshire. At that time, the office of Provincial Grand Master had fallen into disuse, but Dunckerley would personally revive it in several counties. He is known to have been the Provincial Grand Master for Essex from 1776, Dorsetshire and Wiltshire from 1777, and Gloucestershire and Hampshire in 1784. It was at Dunckerley's request that the province of Bristol was created, still unique in English Freemasonry as the only province confined to a single city, and having all of its lodges meeting in the same building. In 1790 he was also made Provincial Grand Master of Herefordshire.

The first evidence of Mark Masonry is in 1769, when Dunckerley, at a Royal Arch Chapter, made several brethren Mark Masons and Mark Masters. It is possible that Dunckerley created the degree.

In 1790 and 1791, Dunckerley projected the centralization of the rather scattered Templar groups in England. On 24 July 1791 he informed the York Encampment of Redemption that he had been invited to assume the office of Grand Master by the Knights Templar of Bristol. York favored the proposal, and in due course Dunckerley accepted the office. The groups referred to his authority in 1791 included The Observance of London, the Redemption of York, the Eminent of Bristol, and the Antiquity of Bath. Dunckerley became the Grand Master of the first national Grand Conclave of "The Royal Exalted Religious and Military Order Heredom, Kadosh, Grand Elected Knights Templar of St. John of Jerusalem, Palestine, Rhodes and Malta".

The encyclopedist Albert Mackey blamed Dunckerley for inventing Royal Arch Masonry, and splitting the third degree in the process, removing the true word of a Mason to the new degree, and losing the original "pure" form of the ritual forever. This is unlikely, as the Royal Arch degree was worked for at least a decade before Dunckerley's initiation.
