Marie Sinclair, Countess of Caithness
Marie Sinclair, Countess of Caithness( 1830 – 2 November 1895), formerly Marie( or Maria) de Mariategui, was a British aristocrat of Spanish descent who married, as his second wife, James Sinclair, 14th Earl of Caithness.
She is particularly remembered for her interest in spiritualism and theosophy and her association with Helena Blavatsky, whose occult successor she claimed to be.
She was born in London, the daughter of a Spanish nobleman, Don José de Mariategui, and his English wife, who was descended from the Earl of Northampton.
Her first husband was General le Comte de Medina Pomar, by whom she had one son, Emmanuel.
On his death in 1868, she inherited a considerable fortune.
She married the Earl of Caithness, by then a widower, on 6 March 1872 in Edinburgh; they had no children.
The earl died in 1881.
In Britain, Marie became interested in spiritualism, attending seances hosted by Florence Cook and taking an interest in the work of Allan Kardec.
She joined the New York Theosophical Society in 1876, and gave financial support to assist in the expansion of theosophy in France.
She met Madame Blavatsky in 1884, when the latter came to France.
In 1889, and perhaps earlier, she was President of the Société Théosophique d' Orient et d'Occident.
The countess was created Duchess of Pomar by Pope Leo XIII in 1879.
In her later years she lived on the Avenue de Wagram in Paris, laying out the rooms like those at Holyrood Palace in recognition of the connection she felt with Mary, Queen of Scots.
She claimed that the queen's spirit had told her that" Men are asleep over the material triumphs they are crowning their brows with, or so buried among the burdens of life, they can not be still and listen to the voice of Deific forces."
Following her death, her son from her first marriage inherited the dukedom of Medina Pomar.
James Sinclair, 12th Earl of Caithness
James Sinclair, 12th Earl of Caithness was a Scottish noble and chief of the Clan Sinclair, a Highland Scottish clan.
James Sinclair was born at Barrogill Castle (Castle of Mey) on 31 May 1766.
He was the son of Sir John Sinclair of Mey, Baronet who he succeeded in the baronetcy in 1774.
He succeeded as 12th earl of Caithness in 1789, as nearest lawful male heir of William Sinclair, 2nd Earl of Caithness.
His claim to the peerage was sustained by the House of Lords.
He was lord-lieutenant of the county of Caithness and lieutenant-colonel of the Ross-shire militia.
He married at Thurso Castle on 2 January 1784 Jane, second daughter of Alexander Campbell of Bareldine who was deputy governor of Fort George.
They had the following children:
George Sinclair, 6th Earl of Caithness
George Sinclair, 6th Earl of Caithness( d. 1676) was a Scottish nobleman and chief of the Clan Sinclair, a Highland Scottish clan in Caithness.
George Sinclair, 6th Earl of Caithness was the son of John Sinclair, Master of Berriedale and his wife Jean, daughter of Colin Mackenzie, 1st Earl of Seaforth.
His paternal grandparents were William Sinclair, Lord Berriedale and Mary, daughter of Henry Sinclair, Lord Sinclair.
William Sinclair, Lord Berriedale was in turn a son of George Sinclair, 5th Earl of Caithness.
George Sinclair, 6th Earl of Caithness married Mary, daughter of Archibald Campbell, 1st Marquess of Argyll, but had no children.
He died at Thurso Castle in 1676.
The Earldom of Caithness being much in debt, he had desponed the estates and the title to his principal creditor, John Campbell of Glenorchy, who upon Sinclair's death was created Earl of Caithness by patent.
This however was challenged by George Sinclair of Keiss, son of Francis Sinclair of Northfield, who in turn was a younger son of George Sinclair, 5th Earl of Caithness.
On 13 July 1680, Campbell of Glenorchy took a force of 800 men north to evict Sinclair of Keiss, who was waiting for him with 500 men near Wick.
Inflamed with drink, the Sinclairs attacked the force of Campbells and were routed in what is known as the Battle of Altimarlach.
Legend has it that so many Sinclairs were killed that the Campbells were able to cross the river without getting their feet wet.
However, in 1681 the Privy Council of Scotland made a proclamation in favor of Sinclair of Keiss who became the 7th Earl of Caithness and Campbell of Glenorchy was created Earl of Breadalbane and Holland.
James Sinclair, 14th Earl of Caithness
James Sinclair, 14th Earl of Caithness,( 16 August 1821 – 28 March 1881), styled Lord Berriedale from 1823 to 1855, was a Scottish Liberal politician, scientist and inventor.
John Sinclair, 11th Earl of Caithness
John Sinclair, 11th Earl of Caithness( d.1789) was a Scottish noble and chief of the Clan Sinclair, a Highland Scottish clan.
John was the eldest son of William Sinclair, 10th Earl of Caithness who died in 1779.
John Sinclair, 11th Earl of Caithness entered the army as an ensign in the 17th Regiment of Foot in September 1772.
On 27 December 1777 he became a major in the 76th Regiment of Foot.
He served for some time in America where he was wounded in the groin by a musket ball while reconnoitering with Sir Henry Clinton at the Siege of Charleston.
Sinclair succeeded his father as earl in 1779 and he held the rank of lieutenant- colonel in February 1783.
( The 76th was disbanded in 1784 in Scotland).
Sinclair died suddenly aged 33 in 1789 in London.
John Sinclair, 11th Earl of Caithness having died in 1789 ended the direct line of the Sinclair of Greenland and Rattar branch of the Clan Sinclair.
The Sinclair of Freswick branch, who descended from William Sinclair of Rattar( d.1663) were the only remaining collateral branch of the Sinclair of Greenland and Rattar branch, and had John Sinclair of Freswick outlived John Sinclair, 11th Earl, he would have succeeded to the earldom.
However, Sinclair of Freswick died in 1784 and the earldom therefore went to Sir James Sinclair of Mey who was a direct lineal descendant of George Sinclair, 4th Earl of Caithness.
