In the 1920s she began thirty years of research and writing about the Elizabethan period of history. She conducted original research using primary sources and she would gather together maps and illustrations to accompany her text. The books were published privately Her work was based on original research using unpublished papers in England and Spain. The books were not initially well received as they failed to give due wight to the prevailing theories of historians. However it has been accepted that many of her insights are convincing.
