Una was the debutante[1] daughter of Commander Edward Stratford Dugdale and his wife, Harriet Ella Portman, who were both supporters of the suffrage movement.

Elsie was the second person to be released under the Prisoners (Temporary Discharge for Ill Health) Act 1913 (the so-called "Cat and Mouse law"),[11] and wife to Hugh Franklin.

[14] The wedding took place at the Savoy Chapel, her father led her down the aisle and Christabel Pankhurst, Constance Lytton and the Pethick-Lawrences attended dressed in WSPU colours.

In 1912, the year Una Dugdale married Victor Duval, publishing her pamphlet "Love, Honour and not Obey" she, too, was painted by Ethel Wright.

Wright painted a full length portrait of Una Dugdale dressed in bright jade with a background of fierce fighting cocks, entitled "The Music Room".

After the First World War, Una Duval co-founded The Suffragette Fellowship, an organisation to preserve the memory of the militant suffrage struggle, of which she was the treasurer.

[16] On 29 January 1955, Una Duval recorded an interview with John Ellison from the BBC Home Service's In Town Tonight describing how she attempted to storm parliament, was beaten in the street by policemen, and spent time in prison, during the campaign for women's votes.
