Sir Simon de Felbrigge served as standard bearer to King Richard II, and his brass effigy holds the royal standard displaying the royal arms of King Richard II (Attributed arms of King Edward the Confessor impaling the royal arms of England). He was appointed a Knight of the Garter, and his brass displays the Garter affixed on his lower leg. Below the shields on the pendant boss of the canopy is Richard II's person badge of the white hart. He largely rebuilt Felbrigg Church, in which survive his coat of arms Or, a lion rampant gules (Burke, Sir Bernard, The General Armory, London, 1884, p.344), sculpted on the butresses of the nave and the spandrels of the west door into the tower. Also surviving in the church is the fetterlock badge, used by the House of York and its supporters, and later used as a crest of the Wyndham family of Felbrigg. (Source: Ketton-Cremer, R.W., Felbrigg, the Story of a House, 1986, p.19 (first published 1962)). The decade of death of Sir Simon de Felbrigge is left blank on the brass, and was never completed. He married secondly Catherine Mallory (d.1461), a daughter of Anketill Mallory of Winwick in Northamptonshire. Sir Simon de Felbrigge and his second wife were buried in the choir of the church of the Dominican Priory in Norwich (later known as Blackfriars' Hall, now known as St Andrew's Hall), of which they were benefactors. By his first wife Margaret von Teschen he had two daughters and co-heiresses, his only children:

• Anne de Felbrigge, a nun at Bruisyard in Suffolk;
• Alana de Felbrigge (d.1458), who married twice: firstly to William Tyndale (d.1426/7) of Deene and Staniern, Northamptonshire (by whom she had 2 sons and 2 daughters) and secondly to Thomas Waweton, of Great Staughton, Huntingdonshire and of Basmey in Bedfordshire, a Member of Parliament.

In 1450 the trustees of Sir Simon de Felbrigge sold the manor of Felbrigg to John Wyndham. (Source: Ketton-Cremer, R.W., Felbrigg, the Story of a House, 1986, p.20 (first published 1962)).
