Its very simple, the Philippines is a vast country, a nation of over 7,100 islands, and only 30% of the islands are actually over the size of 1 square mile, most of the islands in the Philippine Archipelago are so numerous that many don't even have names.
Negros, is actually very well known, there is a large Negrosianos group in New York city, in Queens region, a considerable amount in central new jersey (several thousands) and numerous in California as well. If you're looking for quiet area and nice beaches, then the island of Siqijor or parts of southern Leyte would suit you.
