Grandfather property issue

1 year ago

My grandfather has 2 wives , first wife has 2 sons and one daughter after 3rd child born she ( first wife) died. Then grandfather married another women and she has 2 sons . Now I am first wife second son ' son . My father at the age of 14 his father died and later second wife will see him . After marriage with ky mother they are go to some other place for living . After some year's my father had die then after some years grandmother ( second wife ) also die . No my uncles ( second wife sons ) are staying in a house which is registered land with panchayat which is in the name of my grandfather name, but my uncles changed my grandfather name to grandmother ( second wife ) name after she passes .
Now what are my doubts is
1 . The property is coming to us or not ? In my father school records also my mother name is second wife name itself only .
2. My uncle's are saying this property is belongs to them only and saying that this property is my mother's property we are not giving it to ? Is we are not get that property ?
