According to her Find-a-Grave memorial page and the info on Ancestry, her name was Ida Elizabeth, not Ida Mae. Her obit lists her as Ida E.
I've attached a copy of her obit to her profile.
The obt also lists her daughter as Ina rather than Iva, but I confirmed that her gravestone shows her as Iva. So that is an error or typo in the obit.
