Rajah Matanda

Encounter as Crown Prince of Luzon with Sebastian Elcano, an expeditionary captain for Spain Aganduru Moriz recounts that in 1521, Ache was in command of the Bruneian fleet when they chanced upon what remained of the Magellan expedition, under the command of Sebastian Elcano,

Before he died, Legazpi granted Rajah Matanda's wish that Rajah Sulayman be declared Paramount ruler of Maynila. The unnamed author of the "Anonymous 1572 Relacion" (translated in Volume 3 of Blair and Robertson) explains that this was in keeping with indigenous laws, which allowed inheritances to be passed on to "legitimate" children. While Rajah Matanda did in fact have children, they were not born of his "legitimate wife". The unnamed author of the relacion, explaining the custom as he understood it, says: Rajah Matanda had at least two sons and one daughter: Don Ambrocio Mag-isa Ladyangbata, Don Luis Ylao, and Doña Maria Bolactala.

Dery theorizes as Dery notes:quote|From their vast domains in Manila and Bulacan, Rajah Matanda's descendants were displaced and transferred to the outlying towns of Malate and Ermita. Their appointments as Maestras de Campo, Capitanes de Infanteria, Cabezas de Barangay, etc. brought them innumerable expenses, impoverishment, and imprisonment. Their appointments to said positions forced them to shoulder numerous expenses for and in behalf of the colonial government which the latter failed or conveniently forgot to recompense. The passage of time eventually found the descendants [...] so destitute that they could not even pay the media anata (title fee to be paid before the recipient could enjoy colonial exemption).

He is also sometimes referred to as Raja Laya, Gines de Mafra, and the expedition's scribe Antonio Pigafetta.

Additional details about Raja Matanda are sometimes derived from genealogical accounts which mention him, but these focus on Ache's genealogy, and so do not provide details about specific events.
