Brant was thrice married. By his first wife, Margaret, he had two children, Isaac and Christina, whose descendents are still living. By his second wife he had no issue. His third wife, Catharine, whom he married in 1780, survived him and was forty-eight years of age at the time of his death. She was the eldest daughter of the head-chief of the Turtle tribe, the tribe first in dignity among the Mohawks. By the usages of that nation, upon her devolved the right of naming her husband's successor in the chieftaincy. The canons governing the descent of the chieftaincy of the Six Nations recognize, in a somewhat modified form, the doctrine of primogeniture; but the inheritance descends through the female line, and the surviving female has a right, if she so pleases, to appoint any of her own male offspring to the vacant sovereignty. Catharine Brant exercised her right by appointing to that dignity John Brant, her third and youngest son. This youth, whose Indian name was Ahyouwaighs, was at the time of his father's death only thirteen years of age. He was born at Mohawk village, on the 27th September, 1794, and received a liberal English education. Upon the breaking out of the war of 1812, the young chief took the field with his warriors, on behalf of Great Britain, and was engaged in most of the actions on the Niagara frontier, including the battles of Queenstown Heights, Lundy's Lane, and Beaver Dams. When the war closed in 1815, he settled at "Brant House," the former residence of his father, at Wellington Square. Here he and his sister Elizabeth dispensed a cheerful hospitality for many years. In 1821 he visited England for the purpose of trying to do what his father had failed in doing, viz, to bring about a satisfactory adjustment of the disputes between the Government and the Indians respecting the title of the latter to their lands. His mission, however, was unsuccessful. While in England he called upon the poet Campbell, and endeavoured to induce that gentleman to expunge certain stanzas from the poem of "Gertrude of Wyoming," with what success has already been mentioned.
