There is a branch of the Mendiola family called the familian Gutos.
Gutos means "to snap or break a rope, thread, wire."
Why the family should be called this, I don't know. I have asked a few members of the family, and they don't know. There may be an elderly family member I haven't met yet who may know.
The family was well-known because one of the elders, Tan Chong Gutos, was a techa (prayer leader) at the Hagåtña Cathedral before the war and, after the war, in Sinajaña where they settled.
