Kin Groups and Descent. Kmhmu kinship is characteristically a gens triplex system of prescribed marriage with the matrilateral cross cousin. There are three jeua (lineages) each comprising one or more snta' (totemic clans): the quadruped lineage may include the civet, tiger, gaur, monkey, squirrel, and bear clans; the bird lineage may include the forktail, hornbill, mynah, kite, and kingfisher clans; the plant lineage includes the fern clan. Descent is patrilateral in some regions, bilateral in others. Lineage A takes wives from Lineage B and husbands from Lineage C; Lineage B takes wives from Lineage C and husbands from Lineage A; Lineage C takes wives from Lineage A and husbands from Lineage B.
Kinship Terminology. Kmhmu kinship terminology reflects the asymmetrical-alliance system. The members of the lineage related to Ego as wife givers/husband takers are referred to as e'ém and the members of the lineage related to Ego as wife takers/husband givers are referred to as kheey. Kinship terminology distinguishes kin and affines, parallel cousins, and cross cousins. Kin are distinguished terminologically by gender (except for members of the grandchild and great-grandchild generations). Relative age is marked terminologically for kin of the same gender as Ego.
