Chin (ca. 1800-ca. 1889) was a half-brother to Tall Bull.
Both were the leaders of the Dog Soldiers in the 1850s and
1860s. The mother of the two headmen was indeed a Lakota
woman. Long Chin was a council chief in 1854. In 1863, when
he was already 63, he still led the Dog Men. —
was an 84 year-old Long Chin in the Darlington Cheyenne
census in 1887.
Life of George Bent, he makes reference to the
Dog Soldiers and Spotted Tail's Brules trading with Little
Gerry in 1863, noting that Long Chin was a leader of the
Dog Soldiers and there's a footnoted reference to the fact
that Gerry married one of (the Cheyenne) Long Chin's Sioux
nieces... He was also an uncle of Bent. —
