Weber Utes/Cumumbas are intermarried with Northwestern Shoshone, are linked to Western Shoshone, and appear as a band connected to Ute people of Uintah and Ouray.

According to Steward (1997:627), Western Shoshone territory abutted the “Ute in the Sevier Desert of Utah, at Utah Lake, and, in northeastern Utah…separated from them by the Uintah Mountains, which run east and west.” The larger Western Shoshone territory extended from Death Valley, California through central Nevada into northwestern Utah. Two groups of Western Shoshone, the Goshute, that inhabited the Tooele and Skull valleys and Deep Creek, and the Weber Ute, actually a Shoshone band (also known as Cumumba), that inhabited the Salt Lake Valley have traditional territories within the study area. There is very little information about the Weber Ute as a distinct group, other than they lived along the Weber River. Steward (1997:220) believed that Shoshone bands completely encircled the Great Salt Lake, but early records were confusing as to who these people were, especially those groups living east of the lake in the Salt Lake Valley.

Linguistically, the Shoshone, including the Goshute and Northwestern Band, spoke a language that was part of the Numic branch of the Uto-Aztecan language family. The Weber Ute were thought to have spoken Shoshone (Steward 1997). The Bannock were Northern Paiutes who had migrated from the vicinity of present-day Oregon into southern Idaho and spoke the Paiute language (Murphy and Murphy 1986; Steward 1997).

[Speaking about Ute bands] In 1982, the Uintah and Ouray Ute Indian Tribe published a history of the northern Ute people (Conetah 1982) and provided a map of band names and territories as they are thought to have existed: Pah Vant, San Pitch, Tumpanawach, Cumumba, Uinta-ats, Sheberetch, Yamparika, Parianuche, Taviwach, Weeminuche, Moache and Kapota.

The Cumumba, also known as the Weber Utes, lived along the Weber River and intermarried with the Northwestern Shoshone and became culturally and linguistically connected to the Western Shoshone (Conetah 1982:25; Steward 1997).
