Cultural conventions for naming newborn babies vary around the world and reveal a great deal about social priorities and history.
The Navajo of the US Southwest use their first name and their two clan names when introducing themselves, and they relay their mother’s clan line before the father’s. This tradition shows the tribe’s matriarchal focus. In Spain and most of its former colonies, such as Mexico, babies are given each of their parents’ surnames but the order tends to reflect the patriarchy, with the father’s last name almost always coming before the mother’s.
