Elizabeth and Agnes Thomson were Scottish suffragettes and members of the Edinburgh branch of the Women's Social and Political Union.
On 21 November 1911, they were among the 223 protesters arrested at a WSPU demonstration at the House of Commons, to which they had travelled with other women from the Edinburgh branch, including Jessie C. Methven, Edith Hudson, Alice Shipley and Mrs N Grieve.
In April 1913 the "elderly sisters", along with fellow Edinburgh WSPU members Arabella Scott and Edith Hudson, travelled to Kelso racecourse and attempted to burn down a stand.
None of the women returned to prison when their licences expired and Leneman records that Elizabeth "vanished" after her release, no longer attending WSPU meetings as police actively sought her there.
[7] Agnes continued to be active in the movement, and wrote to the Scottish Prison Service to intercede on Arabella Scott's behalf in August 1913 when she was rearrested under the Cat and Mouse Act at a WSPU protest in London and returned to Calton Jail.
