I just watched this and not for one minute
do I believe Jackie O would have walked around in that house for a minute like in the film. I read a biography about Joseph & Rose Kennedy's children and their spouses and Ethel had a lot to say about how snobby Jackie was back then. No freakin way! I do believe she would have provided a the means for the house to be cleaned up simply to avoid the Bouvier family name being in the press in that embarrassing situation. Onasis wouldn't have given a damn about how it looked in the press While she would have.
I also don't think it was her responsibility to make sure the aunt & cousin was looked after as long as there were immediate family living that were also responsible people. That would be the children,grandchildren and great grandchildren of Phelan Beale & Edith Bouvier Beale.
