Discussion:
AMPAN-19's brother-in-law was Jeronimo Esteve, who in 1962 was the leader of Alpha-66 in Puerto Rico. One of his daughters was Grethel Martinez. Esteve and his sisters were second cousins of Sylvia Odio, whose parents had been imprisoned in Cuba. One of Sylvia Odio's younger sisters, Mary Ann Odio, lived with Grethel Martinez and her husband in Miami. There is an apparent lack of information on Jeronimo Esteve's other sister and her partner Miguel Campos.
