[Extract of Record] - Jeanne De La Riviere or Juana Del Rio
Signature page, Power of Attorney, January 24, 1738 at Presidio Los Adaes:
Those officers and soldiers who knew how to write their own names signed the document, for example, Lt. Joseph Gonzales, Mateo Ybarbo, Philipe de Sierra, Joseph de Acosta, Felipe Bermudes and Marocs Ruiz.
Those who were illiterate, including Juan de Mora, Manuel Chirino, Antonio Cordoves, Domingo del Rio, Francisco de la Cerda and many more, had testigos (witnesses) sign for them. According to historian Francis X. Galán, such power of attorney and many subsequent ones became sources for abuse of the Adaesaño troops.
