Lacandola Documents
The term "Lakan Dula Documents" is used by Philippine historiographers to describe the section of the Spanish Archives in Manila which are dedicated to the genealogical records of the Manila and Tondo aristocracy. As of 2001, only one bundle of twelve folders remains in the archive, the rest having been lost, misplaced, or destroyed by various events such as the Japanese Occupation of Manila during World War II. The surviving bundle is labeled "Decendientes de Don Carlos Lacandola", and scholars use the term "Lacandola Documents" as an informal shortcut.
Scholars specializing in the noble houses of Rajah Matanda, Rajahmuda, and Lakandula mostly use these documents in conjunction with the Archivo General de Indias in Seville, Spain in studying the genealogies of these "noble houses." Other primary sources frequently referred to by historiographers are the Silsila or Tarsilas of Sulu, Maguindanao, and Brunei, and local records of towns where descendants of the three houses may have moved.
