Oh, what I found through a "Google" search of Mrs. Julia M. Barker*, real estate agent in Detroit, Michigan:

"ONCE WORTH A MILLION FIGHTS MURDER CHARGE"
Detroit - Mrs. Julia M. Barker, once reported to have made a million dollars in real estate, sat in a jail last night, faced with the likelihood a first degree murder warrant would be issued against her, and worried over the loss of a dollar bill.
Held in jail since last Saturday in connection with the death of Mrs. Edith Mae Cummings, her friend and partner in many transactions...
Prosecutor Duncan Cameron McCrea said his staff had uncovered evidence to contradict Mrs. Barker's statement that it was Mrs. Cummings who took the pistol used in the shooting to the lonely spot on the banks of the Huron River near Belleville, Mich., Saturday. The pistol had been stolen from a friend of the two women.
--No fingerprints on the gun
--Mrs. Cummings did not wear gloves; if she handled the gun, there would have been prints
--Mrs. Barker wore gloves
The Utica NY Daily Press issue dated Monday, January 17, 1938 mentioned Prosecutor William E. Dowling, and included pictures of Mrs. Cummings & Mrs. Barker.
The St. Petersburg, Florida, newspaper, The Evening Independent, noted that Mrs. Barker wintered in St. Petersburg in its January 17, 1939 issue.
The Evening Independent, January 18, 1938 mentioned the Kentucky land deal that triggered the chain of events leading to Mrs. Cummings' murder. The St. Petersburg Times, February 13, 1938 stated that Arthur McEachern (Mrs. Barker's brother) was extradited from Detroit to Kentucky for the Barker case.
This issue of The Evening Independent, 19 Feb 1938, included a picture of Arthur McEachern as he was remanded into the custody of Mrs. Lena Maiden Craig, a lawyer, and under special commission for Gov. Happy Chandler for the McEachern extradition. Arthur McEachern explained that he was the Secretary/Treasurer for the Wayne County Holding Company, but that the holding company had been absorbed by another company. Originally indicted in the Kentucky land scheme were Arthur McEachern, Mrs. Edith Mae Cummings, Mrs. Julia M. Barker, George W. Brooks, and R. W. McAfee.
The New York Times dated June 18, 1938, noted that "Mrs. Julia M. Barker, former Detroit real estate operator, was sentenced today to serve ten to fifteen years in the House 'of Correction...".
The Ludington Daily News noted that Mrs. Barker was denied new trial, on 2 April 1940, and mentioned that Mrs. Evelyn Fosha had been a witness.
This article mentioned Mrs. James Fosha as the witness as well as an Albert Dolph (this one?) who gave Mrs. Barker a ride to Ida, Michigan, and whose car was left in Dearborn.
The judge in the case was Judge Ira Jayne whose family lived in the Fenton, MI, area.
The Evening Independent of St. Petersburg, in the obituary of Jeannette I. McEachern, on 6 April 1936, identified her sister as Mrs. Julia Barker of Detroit and her brother Arthur McEachern, also of Detroit.

Julia McEachern Barker had her real estate license revoked not long before she shot Edith Mae Cummings. It would be interesting to see what the Archives of Michigan held regarding her license and that of the other parties involved in the Kentucky land dealings.
I do not know when Julia Barker died or what happened to her children or the children of Edith Mae Cummings.
Pauline (Acklen) Landis's husband, Robert, was a real estate broker in Detroit; I'm assuming that's how she (Pauline) came into possession of Julia M. Barker's stationery, but would be interested to know the relationship between the Landis family and the Barker, Cummings, and/or McEachern families, if any.
