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
After Arnold died in 1801, Peggy auctioned the contents of their home, the home itself, and many of her personal possessions to pay off his debts. She died in London in 1804, reportedly of cancer, and was buried with her husband at St. Mary's Church in Battersea on August 25, 1804.
