Joseph Brant
In 1759, Johnson began a common-law relationship with Molly Brant, a Mohawk woman who moved into Johnson Hall and lived with Johnson as his consort for the rest of his life. Molly was the older sister of Joseph Brant who joined the household when he was young. Johnson's relationship with Molly gave him additional influence with the Mohawk. The couple had eight children together, all of whom received land from Johnson by his will. A grandson of William Johnson and Molly Brant was William Johnson Kerr who married Elizabeth Brant a daughter of Joseph Brant and granddaughter of George Croghan.
