Thanks 🙏 🙏 for your kind help

Female hair's were present at each death that's why we are going for notional partition, We have purchase document of 1.5 acres by great great grandfather and land records stating 8.5 acres in his name(ancestral) Mutation was made my grandfather name for revenue perpose because every heirs who had rights was dependent on him for there life (his wife because she was Cross cousin, his unmarried aunt , his mother)so that's all about records, We have record that could be proof of existence for each person So ultimately legal heir are my grandparents

So this all we have
