I looked at the Death Record of her daughter Gertrude at the Mass. Registry of Vital Records and Statistics on 9/30/2016 - it lists her mother's Maiden Name as Bessie Adelson.
The FamilySearch Tree that the SmartCopy Reference goes to shows her as Bessie Adelson
It says 10 sources for that name, if I am reading it correctly
It has Alternate Name -Also Known As - Bessie Sklofsky - 0 Sources
The Marriage Record for her daughter Gertrude - which has been included as a source on her Profile for a while now - has her maiden name as Bessie Adelson.
