Residence: Guevavi

Race or Tribe:  Tudesco (German)

Notes:  Padre Pfefferkorn was an astute observer of Jesuit rules since 21 October 1742. He came to Guevavi on 28 May 1761 from Átil at the age of 35 and stayed for two years.  During those two years, he buried nearly twice as many as he baptized.  At Tumacácori alone, during one four month period, the Padre recorded at least 20 admitted deaths.  Father Garrucho had the ailing Pfefferkorn removed to Oposura in the spring of 1763 for rest.  He was reassigned to Cucurpe.  He went first to Cadiz during the expulsion and then was sent to a monastery where he was held under house arrest.  He was freed late in 1777 through the intercession of the Elector of Cologne.  His most lasting contribution a a missionary is his "Description of Sonora," published in Germany thirty years after he left Guevavi.  He wrote nothing of his two years there.
