 The home of Levi and Catherine Coffin, nicknamed the Grand Central Station of the Underground Railroad, stood just across the Ohio River from Kentucky in the 1800s. It became a stopover for slaves escaping from the South to the Free North. When the Fugitive Slave Act made it illegal to help runaway slaves, they made it clear that, according to Scripture, they were duty-bound to help any individual who came to their door, even under the constant threat of arrest.
