Cryptonym: AMCLATTER-6
It helps to review all of these docs together: 104-10215-10416; 104-10215-10417; 104-10215-10055; 124-10205-10370 (FBI report); 104-10237-10101. In addition, a cable on November 5, 1959, mentioned that AMCLATTER-6's C-Number was C-79496.
Guerra was an FBI informant in Miami from at least the end of 1959 to at least March of 1961.
An FBI memo on Guerra on November 1, 1960, stated that "on October 30, 1960, Mrs. Jane Roman, CIA, advised that the subject had been utilized by CIA in Cuba as a source of information. She was discontinued as a source after she came to the U.S. several months ago. The agency has no plan for any future use of Guerra. CIA has no derogatory information concerning her and she was characterized as a routine type of source."
She was described in a Miami FBI report in February of 1961 as "a Cuban residing in Miami who is acquainted with many of the anti-Castro elements operating in the Miami area." Ana Rosa Guerra's information on the FBI mostly seem to have focused on the MRR, and the splits in that group.

11/20/59: Dispatch from COS, Habana to Chief, WHD (Info: WHD Representative, Miami): Subject: Operational Security Status of AMCLATTER-1 and AMCLATTER-6: "1. In consequence of the information forwarded in reference and previous related correspondence, a security review was instituted on Subjects. As a result, AMCLATTER-1 (Bernard Leon Barker) was reprimanded for unoperational behavior and warned against repetition; AMCLATTER-5 was temporarily taken out of the AMCLATTER net pending the results of the security review; and AMCLATTER-6 was instructed to cease intelligence collection from Bayo's office until it is reasonably certain that no provocation will be forthcoming from him, in a possible attempt to learn the source of the leaks in his office. 2. According to A-1, he did not return to Miami with A-6 and was not debriefed as reference appears to indicate. A-6 went alone to Miami and had the name of (REDACTION) FBI agent, as an emergency contact. Having picked up information regarding a possible attempt to assassinate Esteban Ventura, former police chief under Batista, she got in touch with (REDACTION) FBI agent. 3. Neither A-1 nor A-6 feels in any danger as a result of uncovering the Mendizabal affair. It is to be noted from reference that Mendizabal herself may feel that FBI informant (REDACTION) is responsible for exposing her connection with Bayo. Furthermore, A-6 has since reported that Mendizabal made a 2-hour telephone call from Miami to Bayo in Habana on about 7 or 8 November. Bayo took the call in his office and was overheard to say that he was 'pretty sure of his four office people.' He told Mendizabal that she had been seen going into Cuban Air Force headquarters and that her telephone calls from Miami to his office were a mistake since such calls were easily checked. He told Mendizabal that he was preparing a new telephone number for her using the 'name that her girl friend knows' (A-6 thinks that this name may be Delgado)." (CONTINUED BELOW)
11/20/59: Dispatch from COS, Habana to Chief, WHD (Info: WHD Representative, Miami): Subject: Operational Security Status of AMCLATTER-1 and AMCLATTER-6: "Bayo also told Mendizabal that, if she got into any trouble, she knew where to go to be flown to Cuba. A-6 is of the opinion that Bayo and Mendizabal may have been discussing possible security leaks. 4. It would be of interest if Karnley could ascertain informally if A-6 has reported any information concerning a possible assassination attempt against Ventura to FBI agent. A discreet inquiry at the local FBI office failed to reveal that any such information has recently been received by that office. Andrew F. Merton (probably Jack Stewart)."
