On 2 March he had licence to alienate in mortmain the manor and advowson of Barenton to the masters and scholars of St Michael's, Cambridge.
He was buried in the church of St Michael, Cambridge; during the relaying of the chancel floor in the 1850s, de Stanton's sarcophagus was unearthed.
His foundation of Michaelhouse was eventually absorbed in Trinity College, where Stanton is still commemorated as a benefactor and a memorial chapel survives.
