Henry Jerningham

In the succession crisis of 1553 he was one of the foremost supporters of Mary Tudor, and after her accession was one of her most trusted servants, being appointed Vice-Chamberlain of the Household, Captain of the Yeomen of the Guard, and a member of the Privy Council.

[3][4][5] Through his mother he was a nephew of Elizabeth Scrope (died 1537), who married first William Beaumont, 2nd Viscount Beaumont, and secondly, John de Vere, 13th Earl of Oxford, and also of Margaret Scrope (died 1515), who married Edmund de la Pole, 3rd Duke of Suffolk.

[8][9][10][11] Jerningham's father died in 1515, and by 1532 his mother had married Sir William Kingston, who had been appointed Constable of the Tower of London on 28 May 1524.

[13] He became one of Henry VIII's Gentlemen Pensioners about 1540, and thereafter was present at "major state occasions", and took part in the King's campaign in France in 1544 with his own contingent of five horsemen.

However he was among the first to join the future Queen Mary I at Kenninghall when John Dudley, 1st Duke of Northumberland, attempted to place Lady Jane Grey on the throne after King Edward's death in 1553.

He raised troops in Suffolk on Mary's behalf, and at her accession to the throne she appointed him Vice-Chamberlain of the Household, and Captain of the Guard.
