Context: The Wassamassaw Tribe of Varnertown Indians, is a small state recognized tribe of Native Americans descended from historic tribes of the Colonial Era.  Located in Berkeley County in the Low Country, in 2005 the people were granted recognition as an Indian group by the State of South Carolina, the first stage in recognition as a tribe.  The tribe is headquartered in Berkeley County, South Carolina. The Wanapum tribe of Native Americans formerly lived along the Columbia River from above Priest Rapids down to the mouth of the Snake River in what is now the US state of Washington.  About 60 Wanapum still live near the present day site of Priest Rapids Dam.  The name "Wanapum" is from the Sahaptin "wánapam", meaning "river people", from "wána", "river", and "-pam", "people".  Today they are enrolled in the federally recognized Confederated Tribes and Bands of the Yakama Nation. The Trading Path (a.k.a. Occaneechi Path, The Path to the Catawba, the Catawba Road, Indian Trading Path, Unicoi Turnpike, Warriors' Path, etc.) is not simply one wide path, as many named historic roads were or are.  It was a corridor of roads and trails between the Chesapeake Bay region (mainly the Petersburg, Virginia area) and the Cherokee, Catawba, and other Native-American groups in the Piedmont region of North Carolina, South Carolina, and Georgia.  Indians had used and maintained much of the path for their expansive trading network for centuries prior to its use by Europeans and/or European-Americans.  Indian and later European/European-American settlements occupied key points along the path.  That section of the Trading Path through the Carolina piedmont was also known as the Upper Road, and a portion between North Carolina and Georgia was called the Lower Cherokee Traders Path. Nation Ford Fish Weir is a historic fishing weir located near Rock Hill, South Carolina.  It is one of the few relatively intact Native American fish weirs remaining in South Carolina.  It is a double “V”-shaped rock fish trap or weir located in the channel of the Catawba River upstream from the railroad trestle at Nation Ford.  The weir is located near the Nation Ford Road crossing point of the river and to several documented Catawba people villages. The Chitimacha ( , ; or , ),also known as Chetimachan or the Sitimacha, are a Federally recognized tribe of Native Americans who live in the U.S. state of Louisiana, mainly on their reservation in St. Mary Parish near Charenton on Bayou Teche.  They are the only indigenous people in the state who still control some of their original land, where they have long occupied areas of the Atchafalaya Basin, "one of the richest inland estuaries on the continent."  In 2011 they numbered about 1100 people. Catawba is a town in Catawba County, North Carolina, United States.  The population was 603 at the 2010 census.  It is part of the Hickory–Lenoir–Morganton Metropolitan Statistical Area.  As with the county, the name recalls the Catawba people, the indigenous people who once inhabited the area. Native Americans had been inhabiting the area that is today known as Cary for thousands of years prior to the arrival of Europeans.  When the English colonists arrived in the Piedmont region of North Carolina, they encountered the Sissipahaw, Eno, and Shakori.  Unfortunately, little knowledge remains of these people, but it is believed that their numbers were greatly reduced due to smallpox epidemics and military conflicts with settlers.  It is assumed that they were absorbed by the Catawba people, who still live in North Carolina and South Carolina. The Catawba River (named after the Native American tribes that first settled on the banks) originates in Western North Carolina and the name of the river changes to the Wateree River in South Carolina.  The river is approximately 220 miles (350 km) long.  It rises in the Appalachian Mountains and drains into Piedmont, and is impounded through a series of reservoirs for flood control and hydroelectricity.  The river is named after the Catawba tribe of Native Americans.  In their Siouan language, they identified as the "Kawahcatawbas," "the people of the river". The Catawba, also known as Issa or Essa or Iswä but most commonly Iswa (Catawba: "iswa" - “people of the river”), are a federally recognized tribe of Native Americans, known as the Catawba Indian Nation.  They live in the Southeast United States, along the border of North Carolina near the city of Rock Hill, South Carolina.  The Catawba were once considered one of the most powerful Southeastern Siouan-speaking tribes in the Carolina Piedmont.  The Catawba and other Siouan peoples are believed to have coalesced as individual tribes in the Southeast.  Living along the Catawba River they were named one of the most powerful tribes in the south. This is a list of notable Native Americans from peoples indigenous to the contemporary United States, including Native Alaskans, Native Hawaiians, and Native Americans in the United States.  Native American identity is a complex and contested issue.  The Bureau of Indian Affairs defines Native American as having American Indian or Alaska Native ancestry.  Legally, being Native American is defined as being enrolled in a federally recognized tribe or Alaskan village.  Ethnologically, factors such as culture, history, language, religion, and familial kinships can influence Native American identity.  All individuals on this list should have Native American ancestry.  Historical figures might predate tribal enrollment practices and would be included based on ethnological tribal membership,
