The property that your father inherited through a partition deed along with his brother becomes his self acquired proeprty.
In that case the said property which was bequeathed to you by your father shall be acquired by you after his lifetime by enforcing the Will and this property you acquired by enforcing the Will shall be treated as your self acquired property.
If it was not an ancestral property in the hands of your father then it cannot be considered as an ancestral property in you hands too.
Therefore your daughter's claim for a share in the property on the basis of ancestral property is invalid and not maintainable.
If you properly challenge with the help of a prudent and experienced lawyer, you can get this case case easily dismissed on the basis of the documentary evidences held in your support. .
