Silvester de Everdon (died 1254) was a medieval Bishop of Carlisle and Lord Chancellor of England.
[1][2] In 1244 Everdon became Lord Chancellor (holding the post until 1246)[3] and in 1245 he became the Archdeacon of Chester.
[4] He probably declined the see because of concerns over being rewarded for secular work with a clerical office.
[1] Earlier, Matthew Paris had described Silvester as "the king's faithful clerk, dear and close, obtaining the first place in the chancery, where he served him wisely" and certainly Henry would have had the ability to persuade Silvester to accept the bishopric.
[1] He died in the spring of 1254,[6] after being thrown from a horse[2] near Northampton while on his way to the royal court.
