1815 The First Quadrille at Almack’s Assembly Rooms, London. Left to Right: Marquis of Worcester, Lady Jersey, Clanronald MacDonald and Lady Worcester. “It was not until 1815 that Lady Jersey introduced from Paris the favourite quadrille, which has so long remained popular. I recollect the persons who formed the very first quadrille that was ever danced at Almack’s: they were Lady Jersey, Lady Harriett Butler, Lady Susan Ryde, and Miss Montgomery; the men being the Count St Aldegonde, Mr Montgomery, Mr Montague, and Charles Standish.” From The Reminiscences of Captain Gronow 1810-1860.

The patronesses of Almack’s controlled a lot of a young lady’s acceptance into English society in Jane Austen’s times. To be given a voucher and admitted to an assembly, there was an introduction into London’s polite society.
