During this time, the country was on the brink of war over the slavery issue. Illinois was a hotbed having a southern border with slave states and leaders such as Abraham Lincoln advocating the
abolition of slavery. Having achieved a better life for himself in America, John joined with other abolitionists in the area including Cornelius Kuyper, Charles Dyer, the Dalton brothers, and others to establish a "link" in the Underground Railroad. Fugitive slaves could be hidden at his farm, away from the settlement of Roseland, until safe passage could be arranged to the next underground safe house in Hohman Bridge (
Hammond, Indiana) or possibly with a sympathetic ship captain leaving the Port of Chicago for Canada. In 2000, a community group called the Chicago/Calumet Underground Railroad Effort (C/CURE) was established to research and possibly develop the John Ton Farm site. In 2011, the Jan and Aagje Ton Memorial Garden were established on the grounds of the First Reformed Church in South Holland, Illinois to honor John Ton and all those who supported the underground railroad movement. In 2019, the National Park Service accepted the Jan and Aagje Ton Farm Site to be included in the National Underground Railroad Network to Freedom registry. Following the War in 1867, John sold the farm on the Calumet River and moved to the north side of Roseland to an area known as
Fernwood. He owned of land (8 city blocks) north of 103rd Street and west of Wentworth. He donated the western edge of this land to the
Chicago & Eastern Illinois Railroad to provide commuter rail service to the area from Chicago. In 1893, he built a unique "Dutch Victorian" style home at 316 West 103rd Street. ==Ton Family Reunions==
