A State convention of the league was held in Indianapolis April 12, 1912, and one took place annually after that date, always in the capital. At this convention Dr. Martha Griffiths of Crawfordsville and Dr. Adah McMahon of Lafayette were added to the directors. This year the league affiliated with the National American Woman Suffrage Association.[47] By May, 1916, there were sixty branch leagues and 3,000 members; in May, 1919, there were 300 branches and 16,000 members. Dr. Keller continued as president until the convention of 1917, when Mrs. Richard E. Edwards of Peru was elected and served two years. At the convention of 1919 Miss Helen Benbridge of Terre Haute was chosen. The Franchise League was exceedingly fortunate in its three presidents, who gave the most of their time, thought and effort to its demands without salary. Dr. Keller organized it largely through the force of her own personality and was able to gather around her other strong and determined women through whom the idea of suffrage was carried out into the State. Mrs. Edwards took up the work of more intensive organization of the State outside of Indianapolis and succeeded, with Miss Benbridge as State organizer, in multiplying the branch leagues and the members by five. Miss Benbridge's work as president was that of consolidating these gains and directing the women in the use of the vote which they thought they had won. The list is too long to be given of those who deserve special mention for years of devoted service. From the spring of 1917 to the autumn of 1918 the members of force and character were drawn upon for war service and the league suffered the temporary loss of some of its best workers, who were filling executive positions in the many war agencies. Of the directorate Miss Adah Bush worked first in Washington with the Woman's Council of National Defense and later went to France with the Young Women's Christian Association; Mrs. Fred McCulloch was State chairman of Liberty Loans; Dr. McMahon went to France on the staff of the Women's Oversea Hospitals; Mrs. Henderson was chairman of the "four minute speakers" who at their own expense went over the State speaking for Liberty Loans, Red Cross, etc.
