Alice Chaucer spelled her name "Alyce" in her signed documents (correspondence, deeds and grants).. Alyce owned books in English, French and Latin, and there can be no doubt from a study of her life that she was literate in all three languages. A partial inventory in 1466 lists 21 books among her personal library, including books used for the Mass, song books, books of advice to princes, an epic book of feudal wars in rhymed French, a book on the achievements of admirable women, and one of advice to women, a book "The Pilgrimage of the Life of Man" - an allegory in poetry and prose, and (one of several books commissioned by the Duchess of Suffolk), "Virtues of the Mass".
Birth: Alyce Chaucer was born about 1404-5 (age 11 in 1415),  at Ewelme, Oxfordshire, England, the granddaughter of the famous poet Geoffrey Chaucer.
Alyce (Chaucer) (Philip) (Montague) de la Pole, Duchess of Suffolk, died 20 May (or 9 June) 1475, and was buried at Ewelme, Oxfordshire, England.
Duchess Alyce de Suffolk designed her own unique, canopied, altar tomb, which her son had built entirely of alabaster in St Mary the Virgin Church, a church Alyce and her husband, William de la Pole, Duke of Suffolk, built at the village of Ewelme, Oxfordshire, England.
