To those of you who study genealogy/family history, what was the most interesting discovery that you made while doing your research ?

My cousins traced my dad's side back to England as far back as the late 1500s. Then for some reason we don't exactly know, some family members changed the spelling of the last name in the mid 1600s, and sailed west to Virginia. They migrated south into the Carolinas, and eventually to the midwest. One of my great grandfathers many generations removed (cannot remember his name) was a state senator in North Carolina back in like the 1820s. Another great grandparent many generations removed, was Flanders Callaway, who married Daniel Boone's daughter. And I'm a distant cousin to Bart Starr. That's all I got.
