The papers contain detailed information about the legal and fiscal affairs of the haciendas of Tlapanaloya (Tequixquiac?), Jalapaxco (Chalchicomula), Tepechichilco (Zempoala), and the ingenio of Tuxpango (Orizaba); many other haciendas and properties are mentioned cursorily. The confraternity papers are related to similar papers, also concerning haciendas and mortgages, in the Puebla, Mexico, Hospicia Records. The precise nature of the connection between the Puebla Papers and the confraternity records is not clear, but the documents in Box 1, folder 31 record a formal request by the confraternity for the transfer from Puebla to Mexico of papers relating to litigation involving the estate of the Torija family. Possibly other papers from Puebla eventually came into the hands of the confraternity. Religious organizations in Puebla were involved in the same fiscal activities as the confraternity, and it is possible that Puebla institutions and the Mexican confraternity occasionally held different mortgages on the same properties. The latest item in the confraternity collection is dated 1858.
The collection is open for research.
