There is a book with genealogical data from about 2700 people, ALL descendants of the Corregidores of Querétaro, Josefa Ortíz de Domínguez and Miguel Domínguez. The book is in the Autonomous University of Queretaro Library, there were edited just 1000 copies. I saw it just 2 weeks ago and I read Doña Josefa had not 12 but 14 children. I can go to the Library again, just let me know what specific data you need .
