John Johnston (1775–1861) was an Indian agent in the United States Northwest Territory. He was born on 25 March 1775 near Ballyshannon in the north of Ireland. His father was Scottish and his mother was a Huguenot. He left Ireland when he was eleven years old, travelling to America with a priest and a trusted family friend who was also his tutor. When he emigrated to Pennsylvania in 1786, his father, mother, four brothers, and one sister remained in Ireland. They came to America five years after he settled here.

William Wells, also known as Apekonit, was the son-in-law of Chief Little Turtle of the Miami. He fought for the Miami in the Northwest Indian War. During the course of that war, he became a United States Army officer, and also served in the War of 1812.
