Ji, it is in the year 1972 as per your knowledge. you kept silent for these years whatever the reason. As it is ancestral property, all the legal heirs have equal rights over the property if your grandfather died intestate. so she cannot sell the entire property. however think, your graandfather might have been Gifted the property to your uncle. so apply for EC on "Name Search" on your uncle name and another on your grandfather name. then you may get some information. after getting such information consult a local lawyer for further guidance.

Yes. if your grandfather gifted the property to your uncle, now his legal heirs have right to sell.
