Pls help me find decendants of Filipinos TIZON or ROSALES

I am looking for any information regarding my heritage, especially the TIZON family name. I know the name is originally from SPAIN, but I am Filipino and am looking for either information on my ancestors or decendants. My Father, AUGUSTO B. TIZON married my mother, CONCEPCION C. ROSALES in 1933. My Paternal Grandfather, DOMISIANO TIZON married LUISA BUENAVENTURA (unknown year); my Maternal Grandfather, SOTERO ROSALES married FELICIDAD DELA CRUZ (unknown year). All were married in the PHILIPPINES. I know I have cousins in California, Texas, Maryland, Tennessee and Virginia, but I don't know exactly where. I was told, that either my Great-Grandfather or Great-Great-Grandfather was from Spain, but I have yet to verify that information.

Even if you're not from the Philippines, but have the same family name as one of my grandparents, and you know the history of the name, I would be very intersted in hearing from you. I would especially like to learn more about the TIZON family name (origin and location in Spain).

If you, or anyone you know, has any information regarding relatives (or other wise) of the names above, please have them contact me, or contact me for them. I would be very grateful. Thank you.
