Both young ladies were studying music in Paris, on leave from the New England Conservatory in Boston. Emma voice, and Carrie violin.
When WWI broke out the next year, Emma fled Paris, worried that her German name and many trips to Germany would cause her trouble. After crossing into Germany (not sure how), she was promptly arrested by the Germans, on suspicion of being a French spy. Luckily, German friends sprung her and got her out to England after a short time of worry.
