Does the questioner inherit from his paternal aunt, who died before his father, knowing that she has two sisters and one brother?

It is not clear whether the questioner's father was a full brother to his deceased aunt, or a brother to her from the father's side, or the mother's side. The same applies to the aunt's brothers and sisters: whether they were full siblings, or from the mother's side, or from the father's side. This information affects whether the father is an heir or not. If the father is an heir, his share does not lapse with his death; rather, it passes on to his heirs. The heirs and the detailed distribution of the inheritance can be determined through the aforementioned link.
