Question: What language family does Red Horn and Ho-Chunk have in common?

Context paragraphs:
Winnebago language: The Ho-Chunk language ("Hoocąk, Hocąk"), also known as Winnebago, is the traditional language of the Ho-Chunk (or Winnebago) nation of Native Americans in the United States.  The language is part of the Siouan language family, and is closely related to the languages of the Iowa, Missouri, and Oto.

Red Horn: Red Horn is a culture hero in Siouan oral traditions, specifically of the Ioway and Hocąk (Winnebago) nations.

Quechuan languages: Quechua , also known as runa simi ("people's language"), is an indigenous language family, with variations spoken by the Quechua peoples, primarily living in the Andes and highlands of South America.  Derived from a common ancestral language, it is the most widely spoken language family of indigenous peoples of the Americas, with a total of probably some 8–10 million speakers.  Approximately 13% of Peruvians speak Quechua.  It is perhaps most widely known for being the main language of the Inca Empire, and was disseminated by the colonizers throughout their reign.

Ho-Chunk: The Ho-Chunk, also known as Hoocąągra or Winnebago, are a Siouan-speaking Native American people whose historic territory includes parts of Wisconsin, Minnesota, Iowa, and Illinois.  Today, Ho-Chunk people are enrolled in two federally recognized tribes, the Ho-Chunk Nation of Wisconsin and the Winnebago Tribe of Nebraska.

Austronesian languages: The Austronesian languages are a language family that is widely dispersed throughout Maritime Southeast Asia, Madagascar and the islands of the Pacific Ocean, with a few members in continental Asia.  Austronesian languages are spoken by about 386 million people, making it the fifth-largest language family by number of speakers, behind only the Indo-European languages, the Sino-Tibetan languages, the Niger-Congo languages, and the Afroasiatic languages.  It is on par with Indo-European, Niger–Congo, and Afroasiatic as one of the best-established language families.  Major Austronesian languages with the highest number of speakers are Malay (Indonesian and Malaysian), Javanese, and Filipino (Tagalog).  The family contains 1,257 languages, which is the second most of any language family.

Language family: A language family is a group of languages related through descent from a common "ancestral language" or "parental language", called the proto-language of that family.  The term "family" reflects the tree model of language origination in historical linguistics, which makes use of a metaphor comparing languages to people in a biological family tree, or in a subsequent modification, to species in a phylogenetic tree of evolutionary taxonomy.  Linguists therefore describe the "daughter languages" within a language family as being "genetically related".

Algonquian languages: also Algonkian) are a subfamily of Native American languages which includes most of the languages in the Algic language family.  The name of the Algonquian language family is distinguished from the orthographically similar Algonquin dialect of the indigenous Ojibwe language (Chippewa), which is a senior member of the Algonquian language family.  The term "Algonquin" has been suggested to derive from the Maliseet word "elakómkwik" (pronounced ] ), "they are our relatives/allies".  A number of Algonquian languages, like many of the Iroquoian languages of the hereditary enemies of the Algonquian peoples, have already become extinct.

Long-nosed god maskette: Long-nosed god maskettes are artifacts made from bone, copper and marine shells (Busycon) associated with the Mississippian culture (800 to 1600 CE) and found in archaeological sites in the American Midwest and Southeast.  They are small shield-shaped faces with squared-off foreheads, circular eyes, and large noses of various lengths.  They are often shown on Southeastern Ceremonial Complex representations of falcon impersonators as ear ornaments.  Long and short nosed versions of the masks have been found in ten different states, with the majority found at sites in Illinois.  Many archaeologists now associate them with the Ho-Chunk (Winnebago) stories of the mythological being Red Horn.

Horned guan: The horned guan ("Oreophasis derbianus") is a large, approximately 85 cm long, turkey-like bird with glossed black upperparts plumage, red legs, white iris, yellow bill and a red horn on top of head.  The breast and upper belly are white, and its long tail feathers are black with white band near base.  Both sexes are similar.  The young is duller with smaller horn, and has brown tail and wings.

Tungusic languages: The Tungusic languages (also known as Manchu-Tungus, Tungus) form a language family spoken in Eastern Siberia and northeast China by Tungusic peoples.  Many Tungusic languages are endangered, and the long-term future of the family is uncertain.  There are approximately 75,000 native speakers of the dozen living languages of the Tungusic language family.  Some linguists consider Tungusic to be part of the generally-rejected Altaic language family, along with Mongolic, and sometimes Koreanic and Japonic.
