Claveria Decree List A

Working With the Claveria Decree List A: What You Actually Need to Know

The Claveria Decree List A is the catalog of Spanish surnames distributed across the Philippines in 1863 when Governor-General Narciso Clavería issued a decree standardizing surnames. It is not a single document you can find everywhere. It is a collection of manuscript books scattered across several archives, and the most accessible version is the one digitized by the National Archives of the Philippines and some private genealogy projects. You will find copies on the National Archives of the Philippines website, on certain private family history forums, and in microfilm records at the FamilySearch library. The most complete online version I have come across is the one hosted by the Philippine National Archives that includes the original distribution lists for Manila and several provinces. There is also a PDF compilation some researchers put together from the Archivo General de Indias copies, but those tend to have transcription errors you have to catch yourself. If you are doing serious research, download the highest resolution scan you can find. The handwritten versions have marginal notes and corrections that matter. I spent months matching my grandmother's family surname to a town in Iloilo and almost missed a note in the margin that corrected the municipality name. The digital copy had smudged ink there and I had to pull the microfilm to read it properly.

How the List Actually Works

The decree assigned surnames from a catalog. List A contains the first set of surnames and it is primarily Spanish surnames. List B and the other letters contain additional names. The way it was implemented varied significantly by province. In some areas, every family in a municipality received a surname from the list in a single event. In other places, it was staggered over years and some families never got assigned at all because they lived too far from the municipal center or resisted the order. The most useful thing about the list is that it ties a surname to a specific town. If your ancestor has a Spanish surname and you know roughly which province they came from, you can sometimes narrow down the exact municipality by checking which town received which batch of names. That mapping is not always clean. Some towns received the same surname multiple times from different batches. The list does not tell you which family got which name, only that the name was available in that allocation.

Common Pitfalls Beginners Miss

The biggest mistake people make is assuming every person with a Spanish surname in the Philippines got their name from the Claveria Decree. That is not true. Indigenous surnames existed before 1863. Some families were already using Spanish names from Spanish colonial records, religious baptismal records, or trade. The decree mainly affected native communities that had not yet adopted fixed surnames, particularly in rural areas and island communities. If your ancestor appears in a pre-1863 baptismal record with a Spanish surname, the decree had nothing to do with that name. Another issue is that surnames changed after assignment. People altered them, officials misspelled them during transcription, and some families dropped hyphens or swapped letters to sound more prestigious. I ran into this when researching a lineage. The census record from 1903 showed a surname that did not match the 1870 municipal record for the same person. The difference was a single letter change that the local registrar had made without noting it. You have to cross-reference multiple documents, not just trust one source.

What the List Does Not Tell You

The Claveria Decree List A will not give you dates, parents, or birthplaces. It is purely a catalog. It tells you that a surname existed in the Spanish allocation system and roughly where it was distributed. Nothing more. If you are relying on it to build a family tree, you will hit a wall pretty quickly. You need parish records, civil registration, census data, and land titles to go with whatever the list provides. The list also has gaps. Some provinces have incomplete records of which surnames were assigned where. The original distribution ledgers for certain areas were lost during the war or deteriorated in storage. When those gaps exist, you cannot trace a surname back to a specific municipality using this source alone.

A Practical Workflow

Start with what you already know. Get the full name of your oldest known ancestor and the town they came from. Check civil registration records first, then move to church records going backward in time. If you reach a record from before 1863, the decree is not relevant to that name. If your earliest records are from after 1863, use the Claveria Decree List A to confirm whether the surname appears in the Spanish allocation for that province. Then check if the surname appears in multiple towns, which would mean the list alone cannot narrow things down further. I usually keep a spreadsheet with columns for surname, town, year of first record, and source type. It sounds basic but it prevents you from mixing up two different families with the same surname in different municipalities. I have seen people combine two unrelated lines because both had the same last name and both came from the same province, even though the towns were a hundred kilometers apart and the dates did not align.

The Bottom Line

The Claveria Decree List A is a starting point, not an answer. It is useful for confirming that a surname has a documented presence in the Spanish naming system and for narrowing down which towns to search in next. It is not a substitute for primary records. The gaps, the transcription errors, and the post-decree changes mean you will always need to verify what the list suggests. If you treat it as a reference tool rather than proof, it saves a lot of dead ends. If you treat it as definitive, you will waste months chasing connections that never hold up under scrutiny.
