Thanks for your efforts, I too am a Caballero and just started researching my lineage. I speak some Spanish and hope I can be of assistance.
Useful information I can provide is as follows
Father: Ramon Caballero y Conui (+) Manila, Philippines
Grand Mother: Amparo Conui Caballero
Mother: Aurora Larena Caballero y Fraile (+) Bais, Dumaguete, Philippines
Grand Father: Antonio Larena
My Moms sisters in order of age
Nenuca Anderson y Larena (Andersons from Guam)
Natividad Monserrat y Larena (from Manila, Philippines)
Would it be possible to view what you have? I could share it with family members I am in touch with in the hope that the information we share could be of use to others.
