Your relationship with your grandmother doesn't have any effect on the disposition of her remains. The law, wisely in my view, doesn't attempt to judge the interpersonal relationships and affections of the deceased in the absence of specific direction from her. After all, she is no longer there to testify on her own behalf and the court would only get half the story from the survivors. When the will is silent on the disposition of her remains, her next of kin - not the executor - have the right to determine the disposition of your grandmother's remains. Her next of kin would be her children as a group, if 2 of the 3 agree to give you a small portion, then the 3rd would be powerless to stop them. Since your aunt seems to have possession of the ashes, it might be necessary to go to court to enforce your rights.
