hi there and thanks for writing to me about your search in finding out your part of the family which is the Juarbes, I know Perdo Juarbe is my great uncle which is my grandmothers brother but when you mentioned your grandfather having the same name it doesn't strike me because his father's name is Fernando Juarbe, there are alot of Juarbes in the town of isabela and the only way to find any of them is if you search through the phone books of Isabela, death index or just go there personally which was what I did because my father lives in the next town over, so good luck in your search and take care.
