It lists in alphabetical order all the Filipino names that were not Hispanized and Gumila was in the list. I was interested in finding out because my maiden name is Gumila and my father is from the Lucero/Gumila family from Argao, Cebu. Cayetano Gumila is my great grandfather so I wanted to confirm his origin. My fathers's as well as my aunts' and grandparents' physical features are Spanish so I found it hard to believe that Gumila was an "indio" name. However, I don't see the name in any "Spanish surname lists" either but it doesn't mean that Gumila never existed. It might have just died out just like my brother will be the last Gumila in the family because there are no other sons to inherit the name and my brother unfortunately does not have a son either.
