Property rights of daughters

We are two brothers and three sisters with father and mother having passed away. During lifetime of father, he acquired a site out of own earnings in his name. A portion of the site was sold for meeting expenses of the youngest daughter and also for assisting the other two daughters. The common understanding was that the remaining portion of the site would be shared between the two sons, as the daughters were well provided for and as the two sons had contributed to the family as also taken care of the parents. During their lifetime, a partition suit was filed amongst the brothers of our father, subject matter being ancestral properties at a village. This site was not subject matter of the suit at any time, except that when a property settlement agreement was reached between the litigants [namely the brothers of our father] even the self acquired properties of the brothers was listed in the settlement agreement based on which the partition suit was dismissed as settled out of Court. Now, ten years after passing away of our father, the sisters one and two have filed a partition suit against the two sons and sister number three, claiming that the site is ancestral property and they are eligible for one fifth of the site as also all the other ancestral properties. Our father had executed two wills. In the first will he had willed a portion of the site to the three sisters jointly and revoked the same in the second and last will stating the reasons that the daughters were well provided for and the site was to be shared between the two brothers. This was discussed during life time of our father and all had agreed, verbally. The partition suit was filed in 2012 and is now at issues stage after going through five IAs which were filed for summary judgement. Kindly opine, no just for one side but as a judge would view the issue and order. Thanks and regards.
