History of Surnames in Guam
Origins During Indigenous and Colonial Periods
The history of surnames in Guam is deeply rooted in the island's complex cultural and colonial history. Prior to Spanish contact in the 17th century, the indigenous Chamorro people primarily used personal names and kinship terms rather than fixed surnames. With the arrival of Spanish colonizers, surnames began to be introduced as part of administrative and religious efforts to record inhabitants, leading to the adoption of Hispanic naming conventions.
Evolution Through Colonial Rule and Modern Times
Throughout the Spanish period, many Chamorros adopted Spanish surnames, often influenced by Catholic saints, local officials, or through forced conversions. This practice was solidified with the 1898 Treaty of Paris when Guam was ceded to the United States, which introduced Western legal frameworks, including laws governing names and registration. In the 20th century, American influence further shaped surname practices, blending indigenous naming customs with Western traditions.
Legislative and Cultural Influences
Legislative changes, such as the Guam Civil Code and subsequent laws, formalized surname registration and inheritance. Despite these influences, many Guamanian surnames retain their Hispanic roots, reflecting cultural resilience. Today, surnames serve as markers of identity, history, and family heritage, bridging indigenous, Spanish, and American influences in the island’s cultural fabric.
Etymological Origins of Surnames in Guam
Patronymic and Matronymic Surnames
Many surnames in Guam are patronymic, derived from the names of ancestors or prominent family members.

These names often signify lineage or familial ties passed through generations.
Toponymic and Occupational Surnames
Toponymic surnames are also prevalent, originating from place names or geographic features. Examples include Garcia, which may have roots in Spanish toponyms, and Sanchez. Occupational surnames, though less common, include names like Alvarez, which historically might have signified a family’s association with a particular trade or profession.
Descriptive and Cultural Surnames
Some surnames are descriptive, reflecting physical traits or characteristics, such as Flores (meaning "flowers") or Medina (meaning "city" or "town"). Others are influenced by religious or cultural heritage, with names like Santa Maria or De la Cruz. These diverse origins illustrate the blending of indigenous, Spanish, and later American influences on Guamanian surnames.
Regional Distribution of Surnames in Guam
Surnames in Northern Guam
In the northern regions of Guam, such as Dededo and Yigo, surnames like Taitano and Benavente are common.
