You can read a full transcript of Mary I's will at http://tudorhistory.org/ or in the appendix of J. M. Stone's 1901 book The History of Mary I, Queen of England. The original document, Harleian MS 6949, f. 29, no longer exists.
Here are the key points of Mary's will:
- That her mother Catherine of Aragon's remains be moved from Peterborough and buried with Mary and Mary's "Executors to cawse to be made honorable tombs or monuments for a decent memory of us."
- Provision for alms for the poor and needy and provision for the religious houses of Sheen and Sion which Mary re-established in her reign following their dissolution in her father's reign. She asks for those houses to pray for her soul and those of her husband, mother, father and "all other our Progenitours". Mary also leaves money to the Observant Friars of Greenwich, the Black Friars at St Bartholomews, and various other orders and establishments with requests for them to say "dayly Masses, Suffrages, and Prayers".
- Provision for the "pore Scolers" of the Universities of Oxford and Cambridge, particularly those intending to go into the Church.
- Provision for the Hospital of Savoy, which was established by her grandfather, Henry VII.
