The only problem is that only the South Branch (sort of) flows north. The main course, if anything, heads south. I grew up in Eugene, OR, at the headwaters of the Willamette, which really does flow north. But I don't recall any of my high school chums telling me about the Willamette and the Nile.
How did Saint Margaret of Scotland die? Margaret died on November 16, 1093, at Edinburgh Castle, Scotland, four days after her husband and son died in defense of the castle. Edit
Dying childless on 17 November 1558 she was buried in the north aisle of Henry VII's Lady Chapel. The wooden effigy carried at her funeral still exists but only the head is displayed in the Abbey Museum. Elizabeth I's coffin was later placed on top of Mary's.
