Mary Constance Charteris, Countess of Wemyss and March (née Wyndham; 3 August 1862 – 29 April 1937), styled Lady Elcho from 1883 to 1914, was an English society hostess and an original member of The Souls, an exclusive social and intellectual club.

Early life and ancestry[edit]

Mary Constance Wyndham was born on 3 August 1862 in London at her parents' home in Belgrave Square.[1] She was the eldest daughter of the Honourable Percy Wyndham and Madeline Caroline Frances Eden Campbell. Her paternal grandfather was George Wyndham, 1st Baron Leconfield. Her maternal grandfather was Sir Guy Campbell, 1st Baronet.

She was a great-granddaughter of Irish revolutionary Lord Edward FitzGerald, the son of James FitzGerald, 1st Duke of Leinster. Her great-great-grandmother, Emily FitzGerald, Duchess of Leinster, was one of the Lennox sisters and a daughter of Charles Lennox, 2nd Duke of Richmond.
