Custom, however, may make divorce a simple matter in some societies. Among some Pueblo Indian tribes a woman
could divorce her husband by leaving his moccasins on the doorstep.
Kindred consisted of a set of relatives from each side of the family, extending at least to the second
of any given individual.
A person's kindred was once important, as this was the unit within which inheritance could be claimed, but the
significance of the kindred varied from city-state to city-state and through history. For example, during the 5th and 4th
centuries BC such ties of kinship were less important in urban Athens than elsewhere, because of increasing
urbanization and the large number of noncitizens in the population
is a descent group reckoned through only one parent,
either paternal (patrilineage) or
All members of such a group trace their common ancestry to a single person.
A lineage is exclusive in its membership and is normally corporate, its members exercising rights in common and
being collectively subject to obligations
Membership of a clan is socially defined in terms of actual or purported descent from a common ancestor
This descent is unilineal-—i.e., derived only through the male (patriclan) or the female (matriclan). Normally, but not
always, the clans are exogamous, marriage within the clan being forbidden and regarded as incest. The clan- is a
kinship group of fundamental importance in the structure of many societies.
Affiliation with a group of kin through descent links of one sex
only is called unilineal descent.
Both patrilineality (father's lineage) and matrilineality (mother's lineage) are types of unilineal descent.
In anthropology, phratry is a cluster
of sibs, clans, or kinship groups that have grouped together, either
because they share a belief in a common ancestor or because, even though the sibs or clans are not
actually related by blood, they have adopted common ceremonial and kinship practices.
The term phratry also must refer to three or more groups constituting a tribal society. (With only two such groupings,
the society takes on features of dual organization, and the groups are termed moieties.)
According to a strict definition, moieties are groups that are exogamous (i.e., marriage between members
of the same moiety is forbidden), of unilineal
descent, and in some sense opposed.
Sometimes the term moiety is used more loosely to refer simply to one of two divisions of a society, regardless of
descent or marriage regulation, but in anthropology, the definition is "Either of two kinship groups based on unilateral
descent that together make up a tribe or society."
