History

Tilmubo Island, also referred to as Tilmobo Island, functions as both a distinct geographic islet and an administrative barangay within the municipality of President Carlos P. Garcia in the province of Bohol. The island is situated in the Canigao Channel, a strategic waterway within the broader Bohol Sea. Its administrative history is defined by a series of municipal reorganizations that reflect the evolving governance structure of the eastern coast of Bohol.

Municipal Evolution and Administrative Status

The political identity of Tilmubo Island is inextricably linked to the municipality that governs it. The municipality of President Carlos P. Garcia was not an original settlement but was carved out of the larger municipality of Ubay. This separation occurred in 1969, marking a significant shift in local administration for the eastern coastal communities of Bohol. At the time of this initial separation, the new municipality was named Pitogo, reflecting the name of its central poblacion or main town center.

The administrative boundaries established in 1969 placed Tilmubo Island under the direct jurisdiction of the new local government unit. This change meant that the island’s residents, who were previously part of the Ubay municipal structure, now fell under the governance of the Pitogo municipal council. The transition likely involved the reorganization of barangay councils and the reallocation of local resources, although specific details of the immediate post-1969 administrative adjustments for the island are part of the broader municipal records of the era.

Renaming to President Carlos P. Garcia

In 1977, the municipality of Pitogo underwent a name change to honor Carlos P. Garcia, the sixth President of the Philippines. This renaming was part of a broader trend in Philippine local governance where municipalities were often renamed to commemorate national figures, particularly those with ties to the Visayas region or significant political influence during the mid-20th century. Carlos P. Garcia, a native of Bohol, served as president from 1957 to 1961 and was known for his "Operation Bread Basket" initiative.

The renaming of the municipality to President Carlos P. Garcia did not alter the geographic or demographic reality of Tilmubo Island, but it did cement its administrative identity within the new municipal framework. The island remained a distinct barangay within this renamed municipality. The 1977 change is a key date in the island's administrative history, marking the transition from the name "Pitogo" to the current "President Carlos P. Garcia." This name change reflects the political culture of the time and the local pride in having a native son reach the highest office in the land.

Throughout these administrative changes, Tilmubo Island has maintained its status as a populated islet. The 2020 census recorded a population of 221 people, indicating a small, tight-knit community that has persisted through the municipal shifts of the late 20th century. The island's location in the Canigao Channel continues to define its geographic and economic context, linking it to the maritime activities of the Bohol Sea.

Geography and Physical Features

Tilmubo Island occupies a distinct geographical position within the Canigao Channel, situated in the Bohol Sea. As an islet and barangay under the municipality of President Carlos P. Garcia in Bohol, the island is defined by its compact landmass and specific topographical characteristics. The physical parameters of the island are documented in the table below.
