Thornton and Lucie Blackburn were born as slaves in Kentucky. They would escape, make their way to Canada, establish the legal precedent that led to the Underground Railroad and create the very first cab in the history of Toronto. Learn about their story this week on Muddy York.

I've Got a Home in Glory Land: A Lost Tale of the Underground Railroad by Karolyn Smardz Frost is a good read if you're interested in learning more about the Blackburns.
