In March 1856 the Mexican military packed up Tucson’s civil, military, and church records, taking these documents south to the town of Imuris, in Sonora, Mexico.  One of the soldiers later claimed that some of the records were torn up to make cigarette rolling papers.  Whether this is true remains unknown. Some records were found in a closet of a church in Imuris by Louis Pinart in 1879 and now reside at the Huntington Library in Berkeley, California. The church records for the Tucson Presidio and the San Agustin Mission have never been found, and this made researching family history difficult for the thousands of people descended from the people who lived at the Presidio San Agustin del Tucson in the Spanish and Mexican periods.


J. Homer Thiel became interested in researching Presidio families in 1999, as a result of the archaeological excavations he conducted at the Leon farmstead.  Over the next few years he combed through the surviving records located in Arizona, Mexico, and California.  He found previously unknown documents in Spain. He compiled information on several thousand people who lived in the Tucson Presidio between 1776 and 1856. His research ended with the individuals born up to 1856.  


This book contains all the information Thiel has compiled in the form of biographical sketches of the soldiers, the settlers, and their families, including female members of the family and their spouses, along with complete source citations.
