Christian - ancestral property

This note is to request inputs of lawyers on rights to ancestral property among Christians.

There is a house built on a combination of small plots bought by my father, father' parents, and father' grand parents.

My father has willed this house to me (his son).

Both my mother and father have passed away and i would like to sell the house.

Please advise if any of my sisters / or their children have right to this property. The property is in TamilNadu.

Thank you.
