Margaret Haig Mackworth, neé Thomas, was a Welsh peeress and suffragette. Upon her father’s death, Viscountess Rhondda tried to take his seat in the House of Lords, citing the Sex Disqualification (Removal) Act 1919 which allowed women to enter “any public office”. The Lords’ Committee of Privileges voted strongly against her plea, and she never entered the House of Lords. In 1921 she founded the Six Point Group, pushing for women’s equality in six areas – politics, occupations, morals, society, economics, and law.
