The Countess Cowper (nee the Hon. Emily Lamb) is a historical figure who was a patroness of Almack's. She was born to Peniston Lamb, 1st Viscount Lamb, and his wife the Hon. Elizabeth Milbanke, and she married Peter Clavering-Cowper, 5th Earl Cowper, in 1805. Together they had three sons and two daughters, though the paternity of some is questionable.
After Lord Cowper died in 1837, his widow married Henry John Temple, 3rd Viscount Palmerston, who might have been the father of her daughter Lady Emily Cowper.
Arabella[]
Lady Bridlington thinks to invite her to Arabella Tallant's party, but it is unknown whether she attends, though her fellow patroness Lady Sefton does.
