At Cigom Gifford found 20 houses, mostly of the multiple type so common among the Pomo. Three of the houses held 4 families, three held 3, twelve held 2, and two held 1. The average is 2.35 families per house or, in terms of persons, 11.75 per house. This is of course based on the 1850 value of 5.0 persons per family. If we admit an aboriginal number of 7.0 persons per family, then the number per house becomes 16.45 instead of 11.75. In his study of Redwood Valley Kniffen (1939, pp. 373-380) puts the population at 125 and the number of houses at 12. This would mean 10.4 persons per house, quite close to Gifford's value for Cigom in or near 1850. In his chapter on the Pomo Stephen Powers (1877) described the village of Senel (Sanel, Shanel) in the Russian River valley (p. 168 and map). He shows on his map 104 houses and 5 assembly houses. The houses were large and contained according to his estimate 20-30 persons each. This estimate seems much too high. However, on other grounds he puts the former population at 1,500 inhabitants, a figure which is arrived at entirely independently by an informant of Stewart (1943, p. 45). Indeed Stewart comments with reference to Powers that "my population estimate and description closely approximate his." This means for 104 houses a mean of 14.42 occupants. The average of the three sets of data available give 13.76 persons per house, a figure which may be rounded off at 14.0 in view of the probability that Kniffen's estimate is a little low. It is noteworthy, furthermore, that neither Gifford nor Powers gives any indication that all the houses in the villages respectively studied were not simultaneously occupied. Indeed, with the multifamily system it is difficult to see how they could stand deserted for a considerable period of time.
