Charlie's first wife, Mildred Harris, wrote this series of articles, "The Private Life Of Chaplin" which were published in the Winnipeg Tribune in 1936. They are longer and somewhat more in-depth than the series she wrote in 1927, "Mildred Harris' Own Story," that I posted here about two years ago. In this 1936 series, she offers some interesting tidbits about their life together (i.e. he called her "Millie") and the birth and death of their infant son, some of which were new to me, as well as her own insight into Chaplin the man. See for yourself. I have uploaded a pdf of the articles to my Google Drive site (let me know if you have any problems with the link):
