When signing an official military document, he signed with his full, official title of nobility, Juan Bautista de Anza, followed by his rubric.B) Surname. Just over fifty known documents signed by our subject carry only his surname, Anza, and his rubric. C) Given Name. His friends and family called him Juan, and unofficial letters written to such intimate acquaintances carried this particular signature with his rubric. D) Rubric. All citizens of colonial Spain, regardless of ethnic background or language, had a rubric. It was a well thought-out and practiced squiggly mark that was as unique as the person's signature.
