Origin

Chaucer was born in London, most likely in the early 1340s (by some accounts, including his monument, he was born in 1343), though the precise date and location remain unknown. The Chaucer family offers an extraordinary example of upward mobility. His great-grandfather was a tavern keeper, his grandfather worked as a purveyor of wines, and his father, John Chaucer, rose to become an important wine merchant with a royal appointment. Several previous generations of Geoffrey Chaucer's family had been vintners and merchants in Ipswich. His family name is derived from the French chaucier, once thought to mean 'shoemaker', but now known to mean a maker of hose or leggings.

In 1324, his father, John Chaucer, was kidnapped by an aunt in the hope of marrying the 12-year-old to her daughter in an attempt to keep the property in Ipswich. The aunt was imprisoned and fined £250, now equivalent to about £ 200,000, which suggests that the family was financially secure.

John Chaucer married Agnes Copton, who inherited properties in 1349, including 24 shops in London, from her uncle Hamo de Copton, who is described in a will dated 3 April 1354 and listed in the City Hustings Roll as "moneyer", said to be a moneyer at the Tower of London. In the City Hustings Roll 110, 5, Ric II, dated June 1380, Chaucer refers to himself as me Galfridum Chaucer, filium Johannis Chaucer, Vinetarii, Londonie, which translates as: "I, Geoffrey Chaucer, son of the vintner John Chaucer, London".
