(a) The properties described in schedules A, B, and C in the plaint originally belonged to one Chinnathambi Gounder, the father of the first plaintiff and father of the second plaintiff's father-in-law and great grand father of the third plaintiff. The said Chinnathambi Gounder, executed a settlement deed, at the instance of Devakkal's parents dated 10.09.1934 before the marriage of the said Devakkal with the said Chinnathambi Gounder. Through the said settlement deed, the said Chinnathambi Gounder bequeathed the suit properties to the said Devakkal for the life time and thereafter to her children through him. In pursuance of the said settlement, the said Devakkal took possession of the suit properties and was in enjoyment of the same, till her death on 11.02.1990. After the said settlement, there was a partition between the said Chinnathambi Gounder and his son Vellingiri Gounder, who is none other than the father of the first defendant and father-in-law of the second plaintiff. Even after the partition, the said Vellingiri Gounder gave endless troubles to his aged father Chinnathambi Gounder and schemed to grab the remaining property which were in his possession. Therefore, late Chinnathambi Gounder wanted to make suitable arrangements with respect to the properties covered under the settlement deed after the life time of the said Devakkal. The said Chinnathambi Gounder executed a registered Will dated 20.10.1948 and thereby bequeathed the suit properties, after the life time of Devakkal, to his only daughter, the first plaintiff and to his son's son born through his son's second wife viz., N.V.Natarajan absolutely. The said N.V.Natarajan died leaving behind him,
