Originally part of Potawatomi Native American landscape, the Lombard area was first settled by Americans of European descent in the 1830s. Lombard shares its early history with Glen Ellyn. Brothers Ralph and Morgan Babcock settled in a grove of trees along the DuPage River. In what was known as Babcock's Grove, Lombard developed to the east and Glen Ellyn to the west. In 1837, Babcock's Grove was connected to Chicago by a stagecoach line which stopped at Stacy's Tavern at Geneva and St. Charles Roads. Fertile land, the DuPage River, and plentiful timber drew farmers to the area.
