Property Gifting Matter

My late grandfather made will for the property of farmlands and a house to my 2 aunts (1-Unmarried(now expired) and 1 -Separated(living)). Although there nothing specifically split among 2 aunts, just, in general, the farmland and the house should go to these 2 after my grandfather death and after his demise, none of the 2 aunts divided the property and in time one of the unmarried aunts passed away without making a will or mentioning anything about the property. Now the surviving aunt wants to make a will and gift deed me just the House in my name. Now the Family Hirarchy. My grandFather had 4 Sons (2 surviving) 8 daughters (6 surviving). Now My question is: since among the 2 aunts for whom the will was made by my Grandfather, one of them is dead without claiming her share nor making will, now : 1. Is the surviving aunt the sole owner of the farmlands and the house combined 2. Can she gift deed me the house, without any interference of the rest of her siblings. She is the sister of my Dad.
