I am a journalist researching the life of my cousin Margaretta McGillicuddy Eagar, daughter of Francis McGillicuddy Eagar and his wife Margaret Holden - 1863-1936. She was the governness to the daughters of the last Tsar of Russian and wrote a memoir in 1906. I am looking for any contemporary diaries or letters that mention her or any knowledge of what happened to her after she left Russia.

I would be very grateful for any help.
