Christian unmaried womans property

A christian unmarried woman left a property without a will. She built the house on her own earnings. She had four siblings in this order and none of them are alive now: 1. Sister 2. Brother 3. Sister 4. Brother 5. Youngest sister - This is the woman we are talking about. Now the siblings have children as below: 1. Sister - two sons and a daughter. Both sons are alive but the daughter and her husband are not alive and she does not have children. 2. Brother - no children and his wife is also no more. 3. Sister - Two sons and three daughters. One of the daughters died but her husband is alive. They have a son. 4. Brother - Four sons. All are alive. The question is 1. How will the property be divided? Will all of her siblings' children get equal share or it will be divided by the number of siblings? 2. Will the siblings of the deceased husband of the deceased daughter of the first sister get any share? Thanks
