The Hahamogna inhabited the Verdugo Mountains foothills and San Rafael Hills; the Arroyo Seco in the westernmost San Gabriel Valley area around present day Pasadena and Altadena; and the easternmost San Fernando Valley area north of the Los Angeles River around present day Glendale; all in Los Angeles County, California.
Two settlements named Hahamongna, California have been located. The Hahamogna band have also been called Pascual and Pascualite Indians, after which the 1843 Mexican land grant Rancho San Pascual, that included their part of the Arroyo Seco, was named.
Most correctly Hahamog'na is the name of this tribe's chief, and the tribe's name and the place in which they live also take this name. Other derivatives have been shown in an adjectival style thus referring to them as the "Hahamovic Indians."
Upon his conversion, Hahamog-na was given the Christian name "Pascual" and his tribe became known as the Pascualite Indians, in the Indian Reductions of Mission Indians. - This name preceded the naming of Rancho San Pascual, part of present-day Pasadena, San Marin, and South Pasadena,. The name Hahamongna is now applied to Hahamongna Watershed Park, an archeological site of one of the Hahamongna, California settlements, a recreational area, and an open space nature preserve-park in the upper Arroyo Seco in Pasadena.
Other Tongva tribes
Other family groups of the Tongva could be found elsewhere in the San Gabriel Valley and San Fernando Valley. With the founding of Mission San Gabriel Arcángel in 1773 and Mission San Fernando Rey de España in 1797, these Tongva groups gathered at the missions and were taught European skils of farming, raising cattle and producing leather, tallow, and soap. Once converted to Christianity, the neophytes were generally not permitted to return to village life. Collectively these groups were referred to as Gabrieleños and Fernandeños by the Spanish.
Other Tongva names that are recognizable about the Southland: Cahueg-na (Cahuenga), Topag-na (Topanga), and Azuksag-na (Azusa).
