On 26 May 1455 he was summoned to Parliament as "Johanni Bourgchier de Berners chivaler", and the summons is regarded as creating the title Baron Berners. He attended Parliaments from then until 1472.
He was itinerant justice for Brecon, Wales. From December 1461 to his death he was joint Constable of Windsor Castle, along with Lord Fauconberg.
He died on 16 or 21 May 1474 and was buried at Chertsey Abbey, Surrey. His will was proved on 21 June 1474.
Birth information: about 1415, at Little Eaton [sic], Essex, England
Note: Lewis does not include a citation for the information. The entry for John in Richardson's Royal Ancestry (I:484 BOURCHIER 12.) does not include when or where he was born.
Disputed daughter: A profile was created by GEDCOM import for another child, Anne Bourchier, born 1441, died 1442. There appear to be no reliable sources in the profile, and, unless some come to light, there must be questions about the relationship. I have marked the relationship as uncertain but not detached Anne in case there was a child called Anne who died in infancy. - Michael Cayley, 8 March 2019
Berner/Barnes: "'Berners' is spelt 'Barnes' in some sources, including the 1552 Visitation of Essex. At this date, the 'e' in Barnes would not have been silent, and in some parts of England was pronounced rather like the fill-in word 'er' is today by English speakers who do not roll the letter 'r'.

Bowsey-2 and Bourchier-13 appear to represent the same person because: These profiles have been identified as representing the same person. See reasoning at Space:Bryan family possible fabrication. Bourchier should be LNAB as that is the name by which the family is usually known. Bosey should be OLN.
