Why so many Filipino surnames are Spanish
Most Filipino surnames are Spanish — the legacy of a remarkable event. In 1849, the Clavería decree issued a catalogue of Spanish surnames (the Catálogo alfabético de apellidos) and assigned them to families across the Philippines to standardise names for administration. That’s why names like Dela Cruz, Santos, Reyes and Bautista are so common — and why many are religious.
Indigenous and Chinese roots too
Alongside the Spanish majority are indigenous surnames from Tagalog, Kapampangan and other languages (Magsaysay, Panganiban, Macapagal) and Chinese-Filipino names (Gatchalian), reflecting the country’s layered history.
