This morning I happened upon another episode of This American Life that was all about genealogy! In "The Ghost of Bobby Dunbar,"a woman starts to investigate a family story she grew up with, with very interesting results. It's a really great story, complete with newspaper clippings, court files, finding relatives on the internet, and everything else genealogists enjoy! You see what happens when you're nerdy enough to search "archives" in a radio show's archives? (Wrap your mind around that!) You can download the episode for $0.99 on iTunes, or stream it for free from thisamericanlife.org.
(As a disclaimer, it is a story that demonstrates how genealogy can be "another reason for your family to hate you," which we know, of course, is usually not the case. But when it does happen, it's probably related to stories as cool, as involved, and thus as crucial to relatives' sense of self as this one.)
