X. "Prabhu" is also the title used for kings who ruled in the Hindu/Buddhist era, such as Prabu Siliwangi and Prabu Bratasena. Naming forms Legally, Indonesian personal names are not divided into first and family names. A single name is recognized as a full personal name, and the addition of further components–such as additional given names, regional, or ethnic family/clan names or patronymics or matronymics–is a matter of parents' choice when registering the child's name. Even then, family names or patronymics are just considered part of the full personal name and have no official relevance (for instance, alphabetic ordering of names is always done by the first letter of the full personal name). The majority of Indonesians do not have family names. Rather, their given names are geographically and culturally specific. Names beginning with "Su" in Indonesian spelling ("Soe" in the old orthography) or ending with an "o" are usually Javanese people.
