   User ID: N77.

Marie married Charles Jacques LE MOYNE 3rd Baron De Longueuil on 7 January 1754 in Montreal, Quebec, Canada.¹ (Charles Jacques LE MOYNE 3rd Baron De Longueuil was born on 26 July 1724 in Quebec, Lower Canada, Canada ^{2 5} and died 1755(1756) in Battle of Lake George, New York Province, North America ².)

  Marriage Notes:

"Charles Le Moyne (1st Baron) died in Montreal in 1729, and the barony passed to his son, also named Charles Le Moyne (1687\'961755), the second baron. His son and the third baron, Charles-Jacques Le Moyne (1724-1756), was reported missing in action in the aftermath of the Battle of Lake George, during the Seven Years' War. His wife Marie-Anne-Catherine Fleury Deschambault refused to acknowledge his death until 1759, and shortly after the battle gave birth to twin girls. She married William Grant in 1770, the son of the Laird of Blairfindy, Moray, Scotland. The barony was to be inherited by her surviving daughter, Marie-Charles-Joseph Le Mote de Longueuil, and Grant arranged a marriage to his nephew, Captain David Alexander Grant of the British 84th Regiment. The couple were wed in 1781, and their eldest son became the fifth Baron de Longueuil in 1841."

Marie next married Hon. William GRANT of St. Roch, Deputy Receiver of Quebec, son of William GRANT of Blairfindy, Jacobite 1745 and Jean TYRIE, 11 September 1770 (public Anglican ceremony) in Canada.^{2 3} (Hon. William GRANT of St. Roch, Deputy Receiver of Quebec was born on 15 June 1744 in Blairfindy, Banffshire, Scotland,⁶ died on 5 October 1805 in Quebec, Lower Canada, Canada ⁶ and was buried on 8 October 1805 ³.)

  Marriage Notes:

"...the Hon. William Grant of St. Roch, who was one of the first of the Clan to reach Canada, was Deputy Receiver of Quebec from 1777 to 1784, and a member of the Legislative Council. The latter through his marriage to the dowager Baroness de Longueuil, and his nephew's subsequent marriage with the Baroness, brought about the perpetuation of the only barony of the French regime that has been recognised by the British Crown..."

" It has generally been assumed that the William Grant who was a member of the firm (Robert Grant & Co.) was the Hon. William Grant of St. Roch; for when the Hon. William Grant of St Roch came to Canada as a very young man, he made an abortive purchase from the Marquis de Vaudreuil of a grant of fur-trading rights at La Baye, on Lake Michigan, 'for himself and the firm of Robert Grant & Co.' There are however, in the British Museum series of letters written by the William Grant who was a member of the firm; and from these it was clear that he was a wholly different person, a son of Robert Grant of Tammore and a cousin of Robert Grant of London."

from Grants in Canada by W.S.Wallace




"Seigneuries also being available at low cost, (William) Grant showed an early and constant interest in them. In September 1764 he purchased from François-Joseph de Vienne for 30,000 livres the sub-fief of La Mistanguienne or Montplaisir, and in July 1768 he acquired the seigneury of Aubert-Gallion near Quebec for £100. Grant capped his early drive for the acquisition of seigneuries by marrying Marie-Anne-Catherine Fleury Deschambault, widow of the seigneur Charles-Jacques Le Moyne de Longueuil; having declared himself to be a Catholic, Grant was married secretly at Montreal by the Jesuit Pierre-René Floquet, with special dispensation from Governor Carleton, and publicly on 11 Sept. 1770 by the Church of England minister David Chabrand* Delisle. The union placed at Grant's disposal at least some of the Longueuil seigneurial resources, notably Mingan, and a farm on Île Sainte-Hélène, near Montreal."
