La certificación de armas de la familia Fernández de Jáuregui en México. Un análisis documental y ligatorio

This paper analyzes a manuscript known as “Carta ejecutoria de la familia Fernandez de Jauregui”, preserved today at the National Library of Mexico. A thorough documentary and typological review (including its genealogical and heraldic aspects) permits us to stress the importance of binding as an element of distinction formerly used in administrative documents. An explanation on the differences between a carta ejecutoria and a certificacion de armas and the history of the Fernandez de Jauregui family is also offered. By describing its materials, manufacturing technique, ornamentation and state of preservation, we attempt to establish the possible origin and dating of this type of binding, as well to clarify the reasons of its commissioning by the Fernandez de Jauregui family.
