 They lived in what is now New Jersey and along the Delaware River in Pennsylvania, the northern shore of Delaware, in the northeastern corner of Maryland, the panhandle of Connecticut and the lower Hudson Valley and New York Harbor in New York, at the time of the arrival of the Europeans in the 16th and 17th centuries.The Treaty of Easton, signed between the Delawares and the English in 1766, removed them westward, out of present-day New York and New Jersey and into Western Pennsylvania and Ohio and beyond.The Delawares continually were crowded out by European settlers and pressed to move in several stages over a period of 176 years, with the main body arriving in the northeast region of Oklahoma in the 1860s.
