My name is Charles Villaverde Gagan. If anyone has a query about Gagans in the Philippines maybe I can be of help. My father's grandfather was Spanish with the name of Diego Gagan who became a mayor of Sampaloc, Quezon in the Philippines during the 1800s. At this point, (Diego) I reached the dead end of tracing my family tree. My grandfather, Salvador Gagan, and my father Salvador Gagan, Jr. are both dead.
