Gabriel Christie (16 September 1722 – 26 January 1799) was a British Army General from Scotland, who settled in Montreal after the Seven Years' War.
Gabriel Christie entered the army as an ensign in 1742 under the patronage of his uncle, Lt.-General Robert Napier (1708-1766), Chief Staff Officer to the Duke of Cumberland at the Battle of Culloden.
As Captain of the 44th Regiment of Foot, in 1756 General Abercrombie appointed him assistant-deputy-Quartermaster-General to the Forces in North America, maintaining that position under the new commander-in-chief, Earl Loudoun.
Christie was based in the West Indies during most of the American Revolution, but in the 1780s, when his active role in the army was completed, he settled in Quebec where he had already started with his intentions of becoming a significant Seigneur there.
Christie hired agents to look after his extensive land holdings and lived comfortably in Montreal with his family until his death, despite a few set backs.
During his time in London in the 1780s, he had taken a mistress by the name of Rachel Plenderleath, and by her was the father of three further sons (Gabriel, George and William) who were fully accepted into the main family and provided for equally - they each received £1,500 and commissions in the King's Royal Rifle Corps, while their eldest legitimate brother, Napier, inherited the bulk of his estate, before passing it to his half-brother.
