From Ohio History Central
The Ottawa Indians originally lived along the Ottawa River in eastern Ontario and western Quebec at the time of European arrival in the early 1600s. They moved into northern Ohio around 1740. They were part of the Algonquian Indians and are thus related to the Delaware Indians, the Miami Indians, and the Shawnee Indians. They were enemies of the Iroquois Indians and never really trusted the Wyandot Indians because they were related to the Iroquois.
Political alliances were complicated and changed with the times. Some Ottawas were allies of the French until British traders moved into the Ohio Country in the early 1700s. Many Ottawas moved into northern Ohio so that they could participate in the fur trade with the British. These natives lived in villages along the Cuyahoga, Maumee, and Sandusky Rivers, but the British were not content just to trade. Unlike the French, the British wanted to build forts and towns.
