The network that allowed these women to co-sponsor the petition has been examined. Smedley, Freund, and Whiteley led the petition. Smedley attended the King Edward VI High School as did Thomas and Hartle. Freund was a demonstrator and a lecturer at Newnham College, Cambridge between 1887 and 1912, as were Elizabeth Eleanor Field, Dorothy Marshall, and Mildred Gostling. Thomas, Field, Whiteley, and Gostling spent time at Royal Holloway College, from where there were two additional petitioners: Margaret Seward and Sibyl Widdows. Clare de Brereton Evans and Millicent Taylor attended the Cheltenham Ladies' College, Cheltenham and Taylor had connections with the University of Bristol, where Emily Fortey and Katherine Williams studied. Lucy Boole studied at the London School of Medicine for Women and Katherine Burke studied at University College London under the supervision of William Ramsay - both of these women knew de Brereton Evans. Grace Toynbee studied at the University of Birmingham, and was possibly connected with Hartle. Two petitioners Edith Humphrey and Alice Smith have unknown connections to the remainder, but it is proposed that they were connected by male chemists keen to promote their cause, such William Ramsay.
