Manuscript Collection: Spanish Colonial Manuscript Collections

Collection Overview

Collection summary derived from "Guidebook to Manuscripts", 1969: These are the Hispanic papers collected by G. R. G. Conway, an Englishman who lived in Mexico for many years. They include the records of Inquisition trials for heresy, for charges of Judaism and obeying the Law of Moses, investigations concerning Purity of Faith, relations with the Devil, cursing God, insulting the saints, and questioning the authority of the church. Many of these records are three or four hundred pages in length. Other trial records, not so lengthy, are for fornication, blasphemy, misconduct in office, bigamy, astrology, theft, debt, personal lawsuits over property and inheritance, and a few aimed at securing a title of nobility by proving family descent. A few petitions seeking appointment as commissioner of the Inquisition are included. Items of interest: First Book of Votes (1573-1600) transcript with the sentences imposed of early Mexican Inquisition cases (566 pp.) Instructions for confession to the priests and chaplains (1668-1683, 46 pp.) History of the Discovery of East Indies by Captain Juan Mateo Monje (1720, 246 pp.) Copy of a diary of Father Junipero Serra (1769) and a letter by Father Serra (1774) Diaries of soldiers and friars concerning journeys by land and sea along the coasts of Monterey and California. Many of these papers relate to Hernando Cortes and his son, Martin. There are other Hispanic items which were not acquired as a unit and are not mentioned in the Conway papers. However, all of the Hispanic material is carefully cataloged under a separate cover, compiled by Dr. C. L. Strout of the University of Tulsa.
