Mabel Normand - Could the Illness and/or Death of Mabel's Father, Claude G. Normand, influenced her own Death?

In 1930, Mable's TB condition had worsened. In this same year...her Father, Claude G. Normand was also ill and/or died before her. It would seem that with the illness-death of one, may have influenced the other. There have been cases where one family member died... another family member shortly followed. I now understand, during the funeral of Mable, it was reported or noted that Both Mable's Mother, Mary and her Husband, Lew, stayed very close to one another during Her funeral. This double illness-passing of Claude and Mable soc lose to one another, it must have been a most trying moment for all Members and Friends of "The Normand Family".
