These natives were distributed along the San Joaquin River from its big bend near Mendota to approximately the mouth of the Merced (see map 4, area 5A). The first mention of them is by Moraga in the diary of 1806. He found two rancherias, Nupchenche with 250 people and Cutucho with 400 souls which was "junto a la primera llamada Nupchenche." This means that Cutucho was close to but at that time not necessarily part of Nupchenche. From the description in the diary Nupchenche was situated at or near the mouth of Santa Rita Slough in T9S, R12E, and this is almost exactly where Schenck places it on his map (Schenck, 1926, p. 133). The next visitor who left a record was José Dolores Pico in 1815. On November 7 he left San Luis Gonzaga in western Merced County (in approximately T10S, R8E) and went east to the Tulares at "Arroyo nombrado San Jose," which was close to the rancheria of the Cheneches. At dawn of the 8th he attacked the village and captured 66 persons, but "... la mayor parte de esta gente se fue p^{r} estar dha rancheria en mal parage." The gentiles said that 4 leagues up the San Joaquin River was Nupchenche, thus placing Cheneches on the river in the southern part of T8 S, R11E. This location checks well with the statement made elsewhere in the diary by Pico that Cheneches was near the junction of the San Joaquin and "Las Mariposas," or Mariposa Creek. If Pico captured 66 persons but "the majority" escaped, the total number must have reached from 200 to 400, if not more. Pico then scouted Nupchenche and learned that all the inhabitants had fled. He therefore by-passed the village and went 8 leagues southeast up the San Joaquin to the rancheria Copicha. This rancheria, which by the way must not be confused with the Cutucho of Moraga, was thus located on the river several miles north of Firebaugh, probably near or in T11S, R13E. As a check on this location is Pico's further statement that Copicha was in the valley of the San Joaquin "junto del Tecolote," or the Chowchilla. On November 10 he moved 8 leagues southeast from Copicha and saw horses from the rancheria Tape, which, from the distances, was near Mendota. This view is supported by Estudillo, who saw the region in 1819 and says that the spot "... donde Tape tenia su rancheria" was 24 leagues south of Cheneches and 25 leagues north of Notonto. Actually, Mendota appears to be approximately halfway between these two points. Pico mentions one other village, Malim, which he places near Cheneches. Confirmation is found in a letter of Fr. Marcelino Marquinez (MS) on May 25, 1816, stating that the Cheneches recently have killed two Christians from Malim. The latter rancheria thereupon allied itself with Notoalh and Luchamme. No other trace of the two last-named villages is found.
