They built a house, dug a well, broke forty acres of Great Plains prairie, and raised five children on the American frontier.

In this episode, host Brian maps each of its five elements di...

For millions of African American families, the search for ancestors hits a wall at 1870. Before that year, the federal census did not list enslaved people by name. They appeared only as ages and numbers in slave schedules, as property in estate inventories, as entries without identity. The 1870 census was the first time most formerly enslaved African Americans were documented by name in any federal record. That moment of visibility is where most family history research begins and, too often, ...
