Chamorro Names

Structure & order

Legal/official names follow the Western pattern:

[GIVEN] [MIDDLE/maternal] [SPANISH SURNAME]

Socially, a person is very often identified by their given name plus a clan nickname rather than (or in addition to) the legal surname:

familian [CLAN NICKNAME] → "(of) the family of ___"

See Name Ordering for the general dimension.

Given names

Two layers coexist:

• Spanish / Catholic saints' names: the dominant source since Spanish missionary baptism (José, Maria/María, Juan, Ana, Manuel, etc.). Historically when a person was baptized with a saint's name, that name became the given/Christian name.
• CHamoru given names: persist and are revived today (often meaning-bearing words; the language's modern revitalization encourages indigenous names).
• Nicknames are pervasive: nearly every individual and family has a "better-known-as." Personal nicknames are formed by appending a descriptor to a first name to tell apart multiple people sharing it, e.g. four men named Juan in one branch became Juan Te’, Juan Deda’, Juan Katingting, Juan Donggat (Guampedia).

Gender marking: given names carry gender mainly through their Spanish/Catholic source (José m. / Maria f.); CHamoru itself is not strongly grammatically gendered for names. See Given Names History and Typology.

Family names & patronymics

Spanish surnames. Traditionally CHamorus had no surnames; a person was known by a first name and clan affiliation. Surnames arose under Spain: per the Wikipedia account, CHamorus "were given Spanish surnames through Catálogo Alfabético de Apellidos" (the same Spanish surname-assignment instrument used in the Philippines). Common Chamorro surnames of Spanish origin include Cruz ("cross"), Santos ("saints"), Flores, Castro, Mendiola, Reyes, Perez/Pérez, Salas, Camacho, Borja, Crisostomo, Leon Guerrero, Guerrero ("warrior"), Lujan, Torres, Duenas/Dueñas. A minority of surnames are CHamoru-language words, typically descriptive/action terms, e.g. Taitano (tai "no/non" + tanu "land" = "the landless"), Pangelinan, Manibusan ("to gather/collect"), Aguon, Sablan, Quinata, Chargualaf, Babauta, San Nicolas. See Surname Formation.

Clan nicknames ("familian ___"); the key system. Because so many people share the same Spanish surname (a José Cruz or Ana Dueñas "around every corner"), families are identified by an unofficial family clan name / "better-known-as." The CHamoru genitive familian ("family of") introduces it: familian + clan name. These clan names derive from many things: an ancestor's first name, a surname, the home village, an animal, a physical trait, an occupation/status, or even an embarrassing story. Examples of derivations from Guampedia include Kottis (from Cortez/Torres), Safra (Zafra), Manila/Sambaguenu (Zamboanga, place), Karabau (carabao), Chungi (gray/white hair), Kadada (short), Alkatdi (mayor), Kabesa (leader).

Inheritance. Clan names are inherited and known socially, not legally registered. CHamoru society is matrilineal: ancient CHamorus belonged to the mother's clan, and lineage, land rights and clan obligations descended through the mother's line; the clan is understood as descending from a common female ancestor (Guampedia, Familia). (Caveat: sources describe the matrilineal principle of the ancient/traditional clan; how strictly a given modern family transmits its familian through the mother vs. either side is not uniformly documented and may vary by family.)

How to address someone

Everyday Catholic/Spanish-Pacific norms apply: formal English address uses Mr./Mrs./Ms. + surname; Catholic clergy take Påle’ ("Father") / Father + name. Most distinctively, people are addressed and referred to by familian, in conversation, in obituaries, and in political advertisements, the clan nickname is given (often parenthetically) precisely because the legal surname alone does not identify the person. See Salutations and Address.

Pitfalls for software

• Clan nicknames are absent from legal records. A name parser working from official documents will see only a Spanish surname and miss the familian that actually identifies the family.
• Massive surname collision. A handful of Spanish surnames (Cruz, Santos, Flores, Dueñas, San Nicolas…) cover a large share of the population; surname alone is near-useless for disambiguation, which is exactly why the familian exists.
• "familian X" is not a legal surname. Parsers should treat familian as a clan-marker particle and X as a clan nickname, not as a second surname or a place token (even though X is sometimes a place, e.g. Humåtak).
• Spelling variation: CHamoru vs Chamorro, plus the ñ and glottal-stop apostrophe (Te’, Humåtak); normalization that strips diacritics/apostrophes will corrupt CHamoru-origin names.
• Matrilineal lineage means the family a person "belongs to" may not align with their patrilineal legal surname.
