There is a multi-page report (investigation) on a person named Octavio Paz in the FBI files on Fold3.com (a paid research site). https://www.fold3.com/image/4717713
The report was made 1917-1918 and deals with Mexican banking in the US and this person working for or in support of Zapata. I don't know if this is the same person or not.
