What's in a name? Well, a lot, at least when it comes to piecing together your family history. For former slaves, choosing a last name was one of their first acts of freedom. For Jewish immigrants, it was a way to fit in their new country. Whatever the reason for a name change, it can make the process of learning about one's ancestors difficult, if not impossible. In this episode, we unearth missing links in the family histories of media legend Barbara Walters and educational superstar Geoffrey Canada. Walters did not know her father's real last name. Canada did not know the name of his grandfather. Both of them had been unable to access their history... until now.
