Geoffrey Chaucer,
Chaucer's Works, Volume 1 — Romaunt of the Rose…
“ The spelling 'Ghofrai' is hardly satisfactory; but if Geoffrey be really meant, we gain a piece of evidence of high importance. It proves that Geoffrey bore the same arms as Thomas, and not the same arms as his father John; whose seal displays a shield ermine, on a chief, three birds' heads issuant (The Academy, Oct. 13, 1877, p. 364) . Moreover, the use of Geoffrey's seal by Thomas goes far to establish that the latter was the son of the former.The next link is that Geoffrey Chaucer was succeeded by Thomas Chaucer in the office of forester of North Petherton in Somersetshire ”
