Sieveking was a suffragette and member of the Women's Social and Political Union (WSPU). She participated in the 1911 census boycott, wrote to local newspapers and got caught up in the 1913 Hastings riots when antisuffragists attacked a group of suffrage campaigners on the seafront.[2] When Levetleigh House in St. Leonards-on-Sea was burned down by suffragettes, Sieveking was not involved, but did support the act.[6]
