1. Abstract & Context
Building on colonial records examined in Part 1—from Fausto Obsanga's tax exemption in 1856 to Don Doroteo and Don Cerelo serving simultaneously as Cabeza de Barangay in 1886—a deeper story emerges. When placed in the wider historical context of Spanish rule in the Philippines, these traces strongly suggest that the Obsangas were descendants of a pre-colonial Datu or Maginoo lineage that successfully adapted to colonial administration while retaining genuine local influence in Tibiao.
2. Four Interlocking Pieces of Evidence
First: Onomastic Continuity (The Surname)
Fact: The rare indigenous-sounding name "Obsanga" does appear in the official Clavería surname catalogue of 1849.
Analysis: During this massive reform, most ordinary families were assigned new Spanish or Christian surnames from the official list. Only families with firmly established identity and social standing were usually permitted to keep their original names.
Conclusion: The fact that "Obsanga" was included in the catalogue, combined with its extreme rarity outside one group in Tibiao, indicates that it was already recognized by Spanish authorities as an old, pre-existing family identifier—a kind of heraldic fossil from indigenous times.
Second: Pre-Reform Privileges
Fact: The family enjoyed documented privileges well before the 1863 reform, which began opening the Principalía to newcomers based on literacy and Spanish proficiency.
Analysis: In 1856, Fausto Obsanga was exempted from tribute due to age, and his son Doroteo was already listed as head of a married household.
Conclusion: Such early recognition points to decades of continuous, stable presence in Tibiao and suggests the family was part of the local colonial fabric long before many others entered the elite.
Third: Dual Cabeza Authority (1886)
Fact: In 1886, in a small municipality with only 25 cabecerías, two men bearing the rare surname Obsanga held the highest local office at the same time.
Positions: Don Doroteo served in Cabecería No. 1 and Don Cerelo served in Cabecería No. 25.
Conclusion: This pattern reflects established clan-level dominance rather than the rise of recent arrivals.
Fourth: Co-optation of Pre-Colonial Power
Analysis: Spanish colonial policy in the provinces generally co-opted rather than destroyed pre-colonial power structures. Indigenous leaders known as Datus, Maginoos, and Tumaos were transformed into the Principalía. They collected taxes, organized labor, and maintained order in exchange for preserving many traditional privileges and hereditary influence.
Conclusion: The Obsangas fit this historical pattern remarkably well.
3. Strategic Marriage Alliances
This elite status was reinforced through strategic marriage alliances across generations:
1911 Marriage: Rosela Obsanga y Condino married Clemente Lacson y Songcog.
The Lacson Line: Clemente belonged to the prominent Lacson family with roots in Iloilo.
The Songcog Line: His mother, Doña Juana Songcog, was very likely a daughter of Don Justo Songcog, who served as Gobernadorcillo of Bugasong from 1875 to 1877.
The Española Connection: Through the Lacson line, the family also connected to the respected Española clan of Tibiao, which produced at least five Gobernadorcillos between 1835 and 1890.

5. Summary & Methodological Limits
Taken together, the rare indigenous name, early privileges, simultaneous high offices, and marriage networks paint a coherent picture. While lost parish registers before 1890 prevent absolute proof of every link, the cumulative evidence is compelling. The Obsangas show every sign of descending from an old, locally rooted indigenous leadership lineage that navigated Spanish rule with remarkable continuity.
The story of Fausto, Doroteo, Gregorio, Juan, and Cerelo Obsanga offers a quiet testament to the resilience of indigenous elite traditions in Antique.
