He was of a wealthy Roman Catholic family, and at the age of sixteen was sent by his parents, 'who favoured learning,' to the University of Oxford, proceeding B.A.
On leaving Oxford Green entered the Inner Temple, and after a period of dissipation his earlier impressions revived, and he gave up his worldly amusements.
It was read before the Privy Council, and Green was thrown into the Tower of London on a charge of treason, which broke down.
He was again sent back to prison (to Newgate), but was re-examined (15 January 1555–6) before Bonner and John Feckenham and condemned to be burnt.
A priest (Thomas Whittle or Whitwell), three tradesmen (Thomas Brown, John Tudson and John Went or Winter or Hunt) and two women (Isobella Forster or Annis Foster and Joan Lushford or Jone Lashforde or Warne) were burnt with him.
