For the Southern Wappo Merriam mentions Guiluc (MS "Yukean") and Kaimus. The latter is very well known and is discussed by Barrett (1908, p. 268). The former is in territory which was disputed between the Pomo and the Wappo and may be either _wilikos_ (Wappo) or _Wilok_ (Pomo)--see Barrett's treatment on page 269 of the Ethnogeography (1908). For present purposes it may be considered as Wappo since it was excluded from the Pomo in computing the population of the latter group. Merriam cites no other names, but Barrett gives Annakotonoma and Tsemanoma among the Southern Wappo (1908, p. 269) and Tcimenukme, Tuluka, and Suskol as Wintun villages at the mouth of Napa River. Annakotonoma was known to the missionaries as Callajomanos (and variants), Guiluc as such, and Kaimus as Caymus (and variants). The three Wintun villages have left no trace whatever in the mission records under Barrett's names or any recognizable variants. This is rather surprising, since the area was thoroughly converted by the missionaries at San Rafael and at Sonoma. Very likely the baptisms are in the record but under designations (and there are many) which do not permit the allocation to a specific tribe or village. On the other hand, the area itself is probably included in the appellation "Napa" which appears to have covered the entire region from the present city of Napa to the shore of the Bay. The sum of the recorded baptisms from Caymus, Guiluc, Callajomanos, and Napa is 331. A baptism factor of 25 per cent cannot be employed because the territory of these groups was very close to the Sonoma Mission, and from numerous accounts by contemporary writers we know that missionization was nearly complete. A factor of 50 per cent would give a probable population of 662 and one of 75 per cent a population of 442. Both values are evidently too low. The final resource from which we may seek information is provided by the accounts of the early American settlers. Chief of these is George Yount, who entered Napa Valley in 1831 and took up a grant of land near the present town of Yountville. Yount seems to have been a sober and reliable citizen, and one who was accorded the respect of his fellow pioneers. His story consists of a series of verbal recollections which were written down in manuscript form by a friend, the Rev. Orange Clark, who visited his ranch in 1851. The Clark manuscript, together with other material, has been secured and published by Professor Charles L. Camp (1923). Yount seems to have discoursed at length on the local Indians (1923, p. 55). His description of the tribes follows (I have omitted the explanatory parentheses inserted by Camp).
