She was having an affair with Gene Roddenberry while he was married and he was also fooling around at the same time with Nurse Chapel who later became his wife.
In her later years when she was already suffering from memory loss some ‘fan’ showed up at her door in Los Angeles and over time ended up taking care of things for her, even moving in. Her son did not like what was going on and he found out she had transferred title of her home she had bought some 40 years before to him.
It would now be worth over a million dollars. The son had a lawsuit against him and he also moved her to another state away from him. I do not know the outcome of the lawsuit and who gets the house.
