In February 1859, John Brown traveled across Iowa with 12 escaped slaves. The journey took him along the well worn network of passage known as the Underground Railroad. One of the notable stops was in Grinnell where he was hosted by town founder Josiah B. Grinnell. One of the freedom seekers with him was George Craig, grandfather of Edith Renfrow Smith.
