Will i get a share on my parents/ancestors property

My mother got a share in my grand mother's (fathers mother) property and got it registered both in my mother and brother's name. Both have passed away now. But my mother made a will to pass all her property to my bother and brother's kids. My another two sisters have witness signed it. Now my brother passed away without any kids. My sister in law is claiming ownership of all the property based on will and she got a varisu certificate also from tahshildhar office to claim the ownership. Now can i get a share in ancestors property currently registered in the name of my mother and brother who have passed away even though my mother will states the property should go to brother and brother kids. She also states in will my daughters have no rights in property since she got them married (my marriage expenses were born by my father in law and some gold was given to me by my father when he was alive during my marriage) and got them settled in life. The shocking part is my other two sisters who were well taken care by my brother have witness signed it without my knowledge. I came to know about this will after 16 years of my mothers death. Also my mother got a property with PF money of my father after his death and got it registered in my brother name who was minor at that time. Can i claim a share in this property ?
