Hi,
I am of the San Luis line of the Philippines. I don't know much of the line except that my great great grandmother's name is Carmen San Luis who married Manuel San Jose. I believe they are both of Spanish decent if not true Spaniards. They had a daughter (siblings unknown) Ursula who married Eduardo Guazon. Ursula and Eduardo had 4 children, David, Augusto, Ester and Nene. I don't know if these are their birth names or nicknames.
David married Carolina Solis and had 8 children with her. They are my maternal grandparents.
If any of these names ring a bell, let me know.
Cheers
Connie
