Fugitive slave, Josiah Henson, escaped slavery in 1830 Maryland to live in Ontario, Canada. He established a freedmen's settlement. His autobiography, The Life of Josiah Henson, Formerly a Slave, Now an Inhabitant of Canada, as Narrated by Himself (1849), is thought to be the model for Harriet Beecher Stowe's Uncle Tom's Cabin.
Oh, yeah. Go Seahawks!
