The first female MP? 

Most would say Viscountess Nancy Astor, elected in November 1919 after her husband vacated his seat in the Commons to take up his peerage in the House of Lords.

And they’d be wrong. The first woman elected to Parliament was revolutionary socialist and Irish nationalist Constance Markievicz, who was elected to the British House of Commons in the 1918 General Election from the Dublin jail where she had been imprisoned for her prominent role in the foundational episode of the Irish state - the 1916 Easter Rising.

But by all means - don’t let historical accuracy get in the way of a good tale of aristocratic centralisation of power.
