Great stories behind your sourdough starter?

I'm a science journalist (and a relative newcomer to sourdough baking) looking for stories behind sourdough starters. Has your starter been in your family for generations? Has it been passed around the world?

I'm also curious in those of you who use starters for non-European style breads. If you have great stories to share, please email me at sucramoow [at] gmail.com. Thanks!
