Residency and Lines of Descent
Descent refers to the socially recognized links between ancestors and descendants or one’s traceable ancestry and can be bilateral, or traced through either parents, or unilateral, or traced through parents and ancestors of only one sex. The former occurs in the United States because both paternal and maternal ancestors are considered part of one’s family. The latter, unilateral descent, is practiced in the other 40 percent of the world’s societies (O’Neal 2006).
There are three types of unilateral descent: patrilineal, which follows the father’s line only; matrilineal, which follows the mother’s side only; and ambilineal, which follows either the father’s only or the mother’s side only, depending on the situation. In partrilineal societies, such as those in rural China and India, only males carry on the family surname. This gives males the prestige of permanent family membership while females are seen as only temporary members. U.S. society assumes some aspects of partrilineal decent. For instance, most children assume their father’s last name even if the mother retains her birth name.
In matrilineal societies, inheritance and family ties are traced to women. Matrilineal descent is common in Native American societies, notably the Crow and Cherokee tribes. In these societies, children are seen as belonging to the women and, therefore, one’s kinship is traced to one’s mother, grandmother, great grandmother, and so on (Mails 1996). In ambilineal societies, which are most common in Southeast Asian countries, parents may choose to associate their children with the kinship of either the mother or the father. This choice may be based on the desire to follow stronger or more prestigious kinship lines or on cultural customs such as men following their father’s side and women following their mother’s side (Lambert 2009).
Tracing one’s line of descent to one parent rather than the other can be relevant to the issue of residence. In many cultures, newly married couples move in with, or near to, family members. In a patrilocal residence system it is customary for the wife to live with (or near) her husband’s blood relatives (or family of orientation). Patrilocal systems can be traced back thousands of years. In a DNA analysis of 4,600-year-old bones found in Germany, scientists found indicators of patrilocal living arrangements (Haak, et al 2008). Patrilocal residence is thought to be disadvantageous to women because it makes them outsiders in the home and community; it also keeps them disconnected from their own blood relatives. In China, where patrilocal and patrilineal customs are common, the written symbols for maternal grandmother (wáipá) are separately translated to mean “outsider” and “women” (Cohen 2011).
Similarly, in matrilocal residence systems, where it is customary for the husband to live with his wife’s blood
