I found your message this week, and have some information about Jimmy Chesterfield. I was raised near Waldwick, WI, and the man who owned the land where Jimmy Chesterfield had his little hut, was my Great Uncle, Thomas Gant.
I have the estate settlement, dated Nov. 15, 1927. In it are the names of the living survivors, etc. There is no mention of Mary Jane. If you are interested, please let me know. Sincerely, Ellen
