Anne St John

She was a daughter of John St John, 2nd Baron St John of Bletso and Katherine Dormer, a daughter of William Dormer of Wing, Buckinghamshire.^{[citation needed]}

She married William Howard, 3rd Baron Howard of Effingham in 1597, and was known as "Lady Effingham". He was a son of Charles Howard, 1st Earl of Nottingham and Catherine Carey.

Her daughter's birth in January 1603 was unexpected, according to John Chamberlain.^[1] Elizabeth Howard (1603–1671) married Lord Mordaunt in 1621.^[2]

In January 1605 she performed in the court masque, The Masque of Blackness as Psychrote. She was probably a stand-in for her mother-in-law, Margaret Howard, Countess of Nottingham, who was unwell.^[3]

Her husband died in 1615. Her properties included Donnington Castle, to which the goldsmith and financier Peter Vanlore also had a claim.^[4]

Lady Anne Clifford, a relation, mentions visiting her at the home of Elizabeth Darcy, Lady Lumley on 4 January 1616.^[5] There was discussion in 1619 that Lady Effingham might marry Lionel Cranfield, 1st Earl of Middlesex.^[6]

Anne, Lady Effingham died in June 1638 and was buried in Westminster Abbey.^{[citation needed]}
