that had been my basic thought process with the "San Lazaro" idea--plenty of places have been named based on one tiny geographical feature which ended up being applied to a whole region and then an entire country, so it's entirely plausible that it could happen to the Philippines as wellIf they are conquered by an European kingdom, they will adapt the name of the monarch/dynasty/prince of the moment. It could be called "Barangay", like what happened with Canada.
