of Libon, Albay, Philippines
Salome Calleja is the earliest known matriarch of the clan, with an estimated birth year of 1840 . It is unknown whether she is a native of Libon, Albay; but she definitely settled there at some point in her life.
Her first child, Ignacio was sired by Fr. Gonzales Dietz of the Franciscan order. It is said that the friar so cared for Salome that he handpicked her future husband, Doroteo Serrano, when he was about to return to Spain in the late 1800’s.
She is the great-great-great-grandmother of Senator Juan Miguel “Migz” Zubiri.
