Her other novels include Sir John Hawkwood: A Tale of the White Company in Italy, The Three Bags, The Burgundian: A Tale of Old France, and Harlette (a retelling of her short tale "When the Devil Ruled," which appeared in the April 1913 issue of The Smart Set magazine). Marion Polk Angellotti, the daughter of judge Frank M. Angellotti and his wife, Emma Cornelia Cearley (sometimes mistranscribed as Clearey), worked as a volunteer canteen worker for the American Red Cross from 1918 to 1919, including at an evacuation hospital during the Saint Michel offensive and with the Army of Occupation in Germany. She died in April 1979, at the age of 91, and was interred at Bellevue Memorial Park in Ontario, California.
