After Johnson's death in 1774, Brant and her children left Johnson Hall in Johnstown, New York and returned to her native village of Canajoharie, further west on the Mohawk River. A Loyalist during the American Revolutionary War, she migrated to British Canada, where she served as an intermediary between British officials and the Iroquois. After the war, she settled in what is now Kingston, Ontario. In recognition of her service to the Crown, the British government gave Brant a pension and compensated her for her wartime losses, including a grant of land. When the British ceded their former colonial territory to the United States, most of the Iroquois nations were forced out of New York. A Six Nations Reserve was established in what is now Ontario.
