In reply to:
My grandfather (Alfredo) was from Tagudin, Ilocos, too. I didn't grow up there but from what I know the Lardizabal clan in the Philippines originated there.
BTW, are you a member of friendster (www.friendster.com). I have created an account in friendster to represent the "Lardizabal Family". If you're already a member, you may add firstname.lastname@example.org to your friends list so you can be connected to other Lardizabals in the world. OR if you are not yet a member, you may send me an email (email@example.com) and I'll add you to the "Lardizabal Family" friendster list.
Hope to hear from you. =)
