Do I have any rights concerning my inheiritance?

I live in Pennsylvania, For 2 years prior to her death, I lived in my mothers home and was her only caregiver. My mother was placed in a nursing home and I returned to work. Her will states that any remaining assets after debts are paid be divided equally between her 6 children. I am still living in her house because I am trying to get back on a financial footing before I can afford to find my own place. My siblings have gotten together and told me that I need to be out by the end of October or they will have me removed from the house. Is there anything I can do to keep this from happening? I have never received any documentation concerning the will or what is being done, my one brother is executor and he keeps the rest of my siblings informed about things but not me. Can they legally have me evicted since I am entitled to 1/6th of the house, and would I have the legal right to tell them that they have to buy me out, if they want me gone.
