Additional information from Old Cherokee Familiesby Emmet Starr about early contacts between whites and Cherokees, pp. 466-476:
p. 466 about Christian Priber: "Ludovic Grant, who was said to have been a Scotchman, in a statement recorded on page 301 of the Charlestown, South Carolina probate court in the book of '1754-1758' in a sworn statement of January 12, 1756, says 'It is about thirty years since I went into the Cherokee Country where I have lived ever since...I speak their language.' He married a full blood woman of the Long Hair clan. He was among the Cherokees at the same time that Christian Priber and James Adair [were] in the nation."
pp. 455-7 About Bushyhead: "John Stuart was stationed at Fort Loudon as the Captain of a British company in 1757. The fort was besieged and captured by the war chief Ogonostota on August 7, 1760. Nearly all of the garrison was killed, but Captain Stuart was rescued and taken to Virginia by the civil chief, Atacullaculla. Stuart was later appointed Superintendent of Indian Affairs south of the Ohio River and married Susannah Emory, and their only child was always known as Oonodutu or Bushyhead, and this name has clung to his descendants. Captain Stuart himself was known to his Cherokee acquaintances as Oonodutu on account of his shock of blond hair
So Bushyhead's parents were John Stuart and Susannah Emory. Susannah Emory's grandparents were Ludovic Grant (see note above) and a 100% Cherokee woman of the Long Hair clan. Their daughter married William Emory. Their daughter was Susannah Emory.
P. 467 about Major Downing: "said to have been a major in the British army, married a full blood Cherokee woman of the Wolf clan."
P. 472 about John Gunter: "a Welchman and operated a powdermill in the Cherokee country in 1814."
P. 472 about Chief Doublehead: "Tahlonteeskee was a prominent Chicamauga warrior in 1792. In the United States---Cherokee October 25, 1805 Doublehead, who had hitherto been an implacable war chief was granted three separate tracts of one square mile each and Tahlonteeskee received a square mile of land on the north bank of the Tennessee River, for their influence in negotiating the treaty. This action becoming unpopular, Tahlonteeskee emigrated to the Western Cherokee country where he was elected Principal Chief in 1818." Then on p. 473, "Alexander Sanders killed Chief Doublehead in a drunken brawl at Hiwassee Ferry in the summer of 1807."
P. 475 about Samuel Riley: "Samuel Riley, a White man, married Gulustiyu and Nigodigeyu. They were sisters and belonged to the Long Hair clan."
