Question: How large was the group of Cherokee that Nimrod Jarrett Smith was descended from?
Context: Nimrod Jarrett Smith (1837–1893), or Tsaladihi, was the fourth Principal Chief of the Eastern Band of Cherokee Indians.  He is credited with gaining approval by the North Carolina legislature for the band's incorporation as a legal entity, and for gaining federal recognition as an Indian tribe. The Cherokee Nation (Cherokee: ᏣᎳᎩᎯ ᎠᏰᎵ, "Tsalagihi Ayeli"), also known as the Cherokee Nation of Oklahoma, is the largest of three Cherokee federally recognized tribes in the United States.  It was established in the 20th century and includes people descended from members of the Old Cherokee Nation who relocated from the Southeast due to increasing pressure to Indian Territory and Cherokee who were forced to relocate on the Trail of Tears.  The tribe also includes descendants of Cherokee Freedmen and Natchez Nation.  Over 299,862 people are enrolled in the Cherokee Nation, with 189,228 living within the state of Oklahoma.  According to Bureau of Indian Affairs (BIA) head Larry EchoHawk, the Cherokee Nation is not the historical Cherokee tribe but instead a "successor in interest." Cherokee heritage groups are associations, societies and other organizations located primarily in the United States, which are made up of people who may have distant heritage from a Cherokee tribe, or who may hold a belief that they have such heritage.  Usually such groups consist of those who do not qualify for enrollment in any of the three, federally recognized, Cherokee tribes (The Cherokee Nation, The Eastern Band of Cherokee Indians, or The United Keetoowah Band of Cherokee Indians).  A total of 819,105 Americans claimed Cherokee ancestry in the 2010 Census, more than any other named ancestral tribal group in the Census. The Eastern Band of Cherokee Indians (EBCI), (Cherokee: ᏣᎳᎩᏱ ᏕᏣᏓᏂᎸᎩ, "Tsalagiyi Detsadanilvgi") is a federally recognized Native American tribe in the United States of America, who are descended from the small group of 800 Cherokee who remained in the Eastern United States after the Indian Removal Act moved the other 15,000 Cherokee to the west in the 19th century.  They were required to assimilate and renounce tribal Cherokee citizenship. The Keetoowah Nighthawk Society was a Cherokee Native American organisation formed "ca."  1900 that pledged itself and its followers to return to the traditional "old ways" of Indian life, led by Redbird Smith, a Cherokee National Council and original Keetoowah Society member, and forming in the Indian Territories of present-day Oklahoma.  The Nighthawks arose in response to weakening resolve on the part of Cherokee leaders—including the original Keetoowah Society (Cherokee: ᎩᏚᏩ ᎤᎾᏙᏢᎯ ), a political organization created by Cherokee Native American full bloods, in or about 1859—to continue their resistance on behalf of the Cherokee after the Dawes Commission began forcing the transfer of Oklahoma tribal lands in the Indian Territory to individual ownership in the 1890s (a process termed "allotment").  Soon after forming, the Keetoowah Nighthawk Society grew to as many as 5,500, but they could not forestall the progress of the Dawes Commission, which came to an allotment agreement with Cherokee leaders in 1900; after doing so, the Commission enrolled the generally non-compliant Nighthawks in the tribe without obtaining their consents, registering them for allotments, and, in 1902, arrested Redbird Smith and compelled the same of him. Belonging is an album by American pianist Keith Jarrett which was released on the ECM label in 1974.  It is the first album by Jarrett's 'European Quartet' featuring Jan Garbarek, Palle Danielsson and Jon Christensen.  "Long As You Know You're Living Yours" was the subject of a lawsuit between Jarrett and jazz-rock group Steely Dan: Jarrett alleged that the duo's title track from their 1980 album "Gaucho" had stolen from the song.  Co-writer Donald Fagen later admitted he'd loved the song and was strongly influenced by it.  Jarrett sued for copyright infringement and was then added as a co-author of the song. Sixes, home to approximately 14,540, is an unincorporated community in western Cherokee County, Georgia, United States, located about three miles west of Holly Springs and near the eastern shore of current-day Lake Allatoona.  The community is located in the Georgia Gold Belt, which runs southwest to northeast along the southern edge of the Blue Ridge mountains.  The Sixes Gold Mine, a now-defunct gold mine dating back to the early 19th century, was located just to the northwest.  In addition, the community is home to the Sixes Mill, which was originally built around 1820 by early gold prospectors and later rebuilt "circa" 1880.  The mill has been well preserved and is still located off Sixes Road.  There are two theories on how Sixes derived its name.  The first theory attributes the name to Fort Hinar Sixes, a Cherokee Indian removal fort that was located in the area along the Trail of Tears.  The second holds that the name is derived from an old Cherokee village that was located near the Etowah River named "Sutali" — the Cherokee word for the number six.  Sixes also lent its name to Fort Sixes, an 1830s US Army fort that served as a removal collection point for Cherokee prior to the Trail of Tears.  Sutallee, a community that sits on the opposite side of the Etowah River (now Lake Allatoona) in western Cherokee County, also derives its name from this Native American village.  Today, Sixes is a growing suburban community with many large, upscale residential neighborhoods, including BridgeMill.  The area is served by two elementary schools (Sixes & Liberty); one middle school (Freedom); and two high schools (Woodstock & Cherokee). The Goingsnake Massacre was a shootout that occurred during a trial in the Cherokee court system on April 15, 1872, in the Goingsnake District of the Cherokee Nation.  Ezekial "Zeke" Proctor was being tried for killing Polly Beck and wounding Jim Kesterson in a shooting incident.  The trial was highly charged due to the strong family ties of the accused and victims and because of a jurisdictional dispute between the Cherokee and United States courts.  A federal posse consisting of two Deputy US Marshals, two of their regular posse members, six white men from Fort Smith, and five Cherokee (all relatives of Beck) was sent to attend the trial and to arrest Proctor on federal charges if he was acquitted.  However, shooting broke out in the crowded courtroom during the proceedings, killing eight of the Marshals posse and three Cherokee citizens.  The incident has also been called the Goingsnake Tragedy, the Cherokee Courthouse Shootout and the Proctor-Beck Fight. Immortal was a villainous professional wrestling alliance in Total Nonstop Action Wrestling (TNA).  It originally consisted of leaders Eric Bischoff and Hulk Hogan, as well as Abyss, Jeff Hardy and Jeff Jarrett, and later also came to include Bully Ray, Chris Harris, stable Fortune, Gunner, Hernandez, referee Jackson James, Karen Jarrett, Kurt Angle, Matt Hardy, Mr. Anderson, Murphy, Ric Flair, Rob Terry, Scott Steiner, and Tommy Dreamer.  Jeff Hardy was a two-time TNA World Heavyweight Champion, while Anderson and Angle were one-time TNA World Heavyweight Champions as members of the stable, and Jarrett was also once AAA Mega Champion (referring to himself as the "Mexican Heavyweight Champion") in AAA.  The group was named after both Hogan's long-standing nickname, "The Immortal". The Nimrod Fortress or Nimrod Castle (Hebrew: מבצר נמרוד‎ ‎ , "Mivtzar Nimrod", "Nimrod's Fortress"; Arabic: قلعة الصبيبة‎ ‎ "Qal'at al-Subeiba", "Castle of the Large Cliff", later "Qal'at Namrud", "Nimrod's Castle") is a medieval Muslim castle situated on the southern slopes of Mount Hermon, on a ridge rising about 800 m (2600 feet) above sea level.  It overlooks the Golan Heights and was built with the purpose of guarding a major access route to Damascus against armies coming from the west.
