Griffin, Elizabeth (bap. 1691 -1762), Visitor of Magdalene College, Cambridge

• The Hon Elizabeth Griffin, subsequently Countess of Portsmouth

Daughter of James Griffin, 2nd Baron Griffin of Braybrooke, sister and co-heir of Edward, 3rd Baron Griffin of Braybrooke. She was a direct descendant of Lord Audley.
Her first marriage was to her cousin Henry Neville/Grey; her second in 1741 to John Wallop, MP (1690-1762), governor of the Isle of Wight, 1st Earl of Portsmouth (his second wife).
She secured the Mastership for her husband’s grandon, Barton Wallop; and meanwhile placed George Sandby in office under bond to resign when Barton Wallop was of age – the resignation duly took place in 1774.
Died without issue; the visitorship then passed to her nephew, Sir John Griffin Whitwell, later 1st Baron Braybrooke.
