Peggie and Brant had two children together, Isaac and Christine, before Peggie died from tuberculosis in March 1771.
With Catherine Croghan, Brant had seven children: Joseph, Jacob (1786-1847), John (selected by Catherine as Tekarihoga at the appropriate time; he never married), Margaret, Catherine,[REF] Mary, and Elizabeth (who married William Johnson Kerr, grandson of Sir William Johnson and Molly Brant; their son later became a chief among the Mohawk).
