On Kathleen O'Brennan, the dib.ie says In 1918/19, she undertook a lecture tour in the USA, speaking on Sinn Féin, the place of women in the Irish republic, and Feis Ceoil.

From Wikipedia:
According to research by historian Catherine M Burns, O'Brennan arrived in America in October 1914 and stayed there for longer than expected due to the difficulty of transatlantic travel during the First World War. Working as a journalist and lecturer, O'Brennan traveled to California and Oregon and spoke to women's organisations as an authority on the Gaelic league and Irish art and culture.

Her lectures included details she got from her sisters and photos of Éamonn Ceannt and his son, Rónán.

... She became involved in the IWW through Dr Marie Equi, with whom she had a romantic relationship. When Equi was arrested, O'Brennan worked to see her released and continued to agitate until her own arrest in 1919 during the Red Scare....

O'Brennan founded the Women's Irish Education League in San Francisco in May 1919.
