Table schema:
CREATE TABLE table_name_64 (martyred INTEGER, canonised VARCHAR, beatified VARCHAR, name VARCHAR)

Question: When was John Hoan Trinh Doan / St. John Hoan, who was beatified in 1909 and canonised after 1988, martyred?
SQL: SELECT MAX(martyred) FROM table_name_64 WHERE beatified = 1909 AND name = "john hoan trinh doan / st. john hoan" AND canonised > 1988
