M (Man-, Mang-) surnames of Carcar
The Man- subgroup is distributed in the Perrelos-Daanglungsod area. It should not be surprising that a lot of Sangat-Perrelos families originated from Bohol since Sangat is a fairly large cove that would certainly be a beacon for travelers from Bohol. Meanwhile, the Mang- families are fairly bunched around the Napo hills bounded by present-day Guadalupe.
Of course it baffles us how an alphabetical group in the catalogo was distributed to settlements as far apart from each other as Perrelos-Daanglungsod and Napo. And because of this distant application, it would seem safe to assume (for the sake of assuming) that the Man- and the Mang- surnames were also treated differently, and not one whole letter, by the implementers of the Claveria decree in Carcar.
Bernardo Manguiran, a resident of Napo and then known as Bernardo Agustin, was a cabeza de barangay in the 1820s. His collateral descendant, Jose Ricare Manguiran, whose family had migrated to Bukidnon, was consecrated a bishop in 1987 and is the bishop of Dipolog.
