Oxford DNB (Chaucer, Geoffrey; poet and administrator; b. probably in the early 1340s, though neither birth date nor place are certain; in Oct. 1386 in trial testimony he described himself as "forty and more"; the precise date of 1343 sometimes given is based on the assumption that at the time of the trial he was 42 or 43; no record of him after June 5, 1400; the traditional death date, Oct. 25, 1400, from an inscription placed on a tomb in Westminster Abbey in 1556, may be correct)
