The first inhabitants of what would become the village of Lincolnshire were Native American Potawatomi migrants from Canada and Wisconsin. The tribesmen left these northern places in the 16th century in search of a warmer, more temperate climate. The first Europeans to visit the area were the French Jesuit explorers Father Jacques Marquette and Louis Jolliet. Shortly after arriving in 1673 at the site of what later became Waukegan.The first white settler in the Lincolnshire area was Captain Daniel Wright, who arrived in 1834. The Potawatomi tribesmen were ousted a year later in the 1833 Treaty of Chicago, which was implemented two years after its ratification, and faced relocation.The Lincolnshire area was originally a part of the town of Half Day.
