While families include people who are directly related to each other, clans are composed of all people who are descendants of the same ancestral clan grouping. Like many Native American nations, the Muscogee Creek are matrilineal; each person belongs to the clan of his or her mother, who belongs to the clan of her mother. Fathers are important within the family system. But, within the clan, it is the mother’s brother (the mother’s nearest blood relation) who functions as the primary teacher, protector, disciplinarian and role model for children, especially for boys. Clan members do not claim "blood relation" but consider each other as family due to their membership in the same clan. This is expressed by their using the same kinship titles for both family and clan relations. For example, clan members of approximately the same age consider each other "brother" and "sister", even if they have never met before. Muscogee clans are as follows, an asterisk indicates extinction:34
