Geoffrey Chaucer occupies a unique position in the Middle Ages. He was born a commoner, but through his intellect and astute judgments of human character, he moved freely among the aristocracy. Although very little is definitely known about the details of his life, Chaucer was probably born shortly after 1340. Although the family name (from French "Chaussier") suggests that the family originally made shoes, Chaucer's father, John, was a prosperous wine merchant.
Both Chaucer's father and grandfather had minor standing at court, and Geoffrey Chaucer's own name appears in the household accounts of Elizabeth, Countess of Ulster and wife to Prince Lionel. As a household servant, Chaucer probably accompanied Elizabeth on her many journeys, and he may have attended her at such dazzling entertainment as the Feast of St. George given by King Edward in 1358 for the king of France, the queen of Scotland, the king of Cyprus, and a large array of other important people. Chaucer's acquaintance with John of Gaunt (fourth son of Edward III and ancestor of Henry IV, V, and VI), who greatly influenced the poet, may date from Christmas 1357, when John was a guest of Elizabeth in Yorkshire.
