Note 1 — Petition for Aid to the Seminary of San Juan de Letran

This man undertook, as a work of charity, to rear and educate orphaned or poor Spanish boys, for which purpose he collected aims; and later he secured from the crown the aid for which these letters ask. Having spent his life in this work, Guerrero at his death (being then a Dominican friar) placed this school in charge of the Dominicans, who accepted it—on June 18, 1640, organizing it as the college of San Juan de Letran; it became a department of their university of Santo Tomás.
