The Cebu City families of Carcar
More than any other town in Cebu, Carcar attracted a huge number of migrants from Cebu City (including the most numerous, the mestizos sangleys), San Nicolas (when it was still a separate town independent of the city), the biggest contingent that is Bohol, and the other towns north and south of Carcar. These families have since intermarried with each other and with older Carcar families as well as with other migrant families from other parts of the Visayas and Luzon.
The mestizo sangley families who arrived in Carcar (presumably all from Parian) are Alcorcon, Alcudia, Aldocente, Alo, Avila, Barcenilla, Cui, Cuico, Florido, Gantuangco, Garces, Gemperoso, Jaen, Medalle, Mercado, Navasquez, Noel, Nuñez, Rayla, Regis, Sagolili, Sarmiento, Sobrevilla, Solon, Suico, Urgello, Vasquez, Velez, Veloso, Villarosa and Yap. Records for mestizos Sangleys from Parian already appear in Carcar church records by the 1820s.
Other Cebu City families (some of whom may have had mestizo sangley origins but the link is unclear from Carcar records) are the Alegrado, Apura (Mabolo), Base, Buntia, Cabalquinto (Pardo), Cacafranca, Gabrillo (Pardo), Lapasaran, Lauron (Talamban), Lauronal, Montesclaros, Poncardas, Purcia (Mabolo). Records can be found for the Alegrado family also in the 1820s.
Meanwhile, when San Nicolas was still a town independent from Cebu City, many of its people had already transferred residence to Carcar, a number even before the Claveria Decree in 1849-1850. Count among the San Nicolas families Abella, Abellana, Abellaneda, Abellanosa, Aguilar, Aldave, Atillo, Babao, Bacalso, Baclay, Bacon, Binoya, Borres, Caballero, Caballes, Cavan, dela Cerna, Enriquez, Gutierrez, Macasero (also from Mabolo), Nacua, Nadela, Padin, Racho, Rama, Ramos, Verano (via Aloguinsan) and Yburan. Although records for San Nicolas families can be found even before 1820, these have no surnames yet and have not yet been traced forward to present families in Carcar. The earliest records for a family listed above seem to be for the Aldave family, with children born in the 1830s.
I may have missed some families here and there but…
It is possible that in the distribution of surnames for San Nicolas went the Ab-, the Bac-, the Cab-.
