At some time in the 1780s, after the US achieved independence, Point du Sable settled on the north bank of the Chicago River close to its mouth.[24][n 3] The earliest known record of Point du Sable living in Chicago is an entry that Hugh Heward made in his journal on 10 May 1790, during a journey from Detroit across Michigan and through Illinois.[27] Heward's party stopped at Point du Sable's house en route to the Chicago portage; they swapped their canoe for a pirogue that belonged to Point du Sable, and they bought bread, flour, and pork from him.[28] Perrish Grignon, who visited Chicago in about 1794, described Point du Sable as a large man and wealthy trader.[29] Point du Sable's granddaughter, Eulalie Pelletier, was born at his Chicago River settlement in 1796.[30]
