Macro-Siouan languages
In the 19th century, Robert Latham suggested that the Siouan languages are related to the Caddoan and Iroquoian languages. In 1931, Louis Allen presented the first list of systematic correspondences between a set of 25 lexical items in Siouan and Iroquoian. In the 1960s and 1970s, Wallace Chafe further explored the link between Siouan and Caddoan languages. In the 1990s, Marianne Mithun compared the morphology and syntax of all the three families. At present, the Macro-Siouan hypothesis based on relations among Siouan, Caddoan, and Iroquoian is not universally accepted as proven.
Southern Sierra Miwok
Southern Sierra Miwok (also known as Meewoc, Mewoc, Me-Wuk, Miwoc, Miwokan, Mokélumne, Moquelumnan, San Raphael, Talatui, Talutui, and Yosemite) is an Utian language spoken by the Native American people called the Southern Sierra Miwok of Northern California. Southern Sierra Miwok is a member of the Miwok language family along with Lake Miwok, Coast Miwok (extinct), Saclan (extinct), Plains Miwok (extinct), Northern Sierra Miwok and Central Sierra Miwok. The Miwok languages are a part of the larger Penutian language stock. The original territory of the Southern Sierra Miwok people is similar to modern day Mariposa County, California. The Southern Sierra Miwok language is nearly extinct with only a few speakers existing today. However, as of 2012, an active revitalization program is underway.
