The gold rush attracted lots of people to Colorado -- most of them looking for fortune. Clara Brown came looking  for her daughter. Brown was a newly freed slave and had lost track of her daughter, who was sold to another master. Clara Brown went on to become a highly respected land owner and philanthropist, but the search for her children consumed her.

Clara Brown is the subject of a new documentary from PBS' "To the Contrary" called "Clara -- Angel of the Rockies." Director Patricia McInroy spoke with Colorado Matters host Ryan Warner.
