Johnson was elected as a hereditary chief of the Six Nations, succeeding his mother's brother, Henry Martin of the Wolf clan. The Mohawk had a
matrilineal kinship system, in which descent and property passed through the woman's line, and his mother nominated him for the post. He later became friends with
Jasper Tough Gilkison, Upper Canada Superintendent to the Six Nations. He was appointed government interpreter. Johnson served as a timber ranger, making efforts to control the theft of timber and sale of
whiskey on the reserve by unscrupulous non-native men. He was badly beaten in 1865 for this, and attacked again in 1873, when he was shot. The sale of timber and whiskey was lucrative for whites. In 1884 Johnson died at his estate Chiefswood on the Grand River near Brantford. It has been listed as a
National Historic Site and is the only Native mansion surviving from the pre-Confederation years. The house and summer kitchen wing were restored in the early 21st century. In addition, much of the open grounds have been restored since the late 20th century to the Ontario Tall Grass Prairie Meadows that were characteristic at the time of the family's residence and had plants used by the Mohawk for medicinal purposes. Today less than five acres remain associated with the mansion. Other parts of the more than 200-acre estate were sold by heirs over the years. ==See also==
