Mr. Bennet's heir is Mr. Collins.
Though Mr. Bennet has five daughters, none can be the heiress, because the estate is entailed. The entailment states that the heir has to be male. The result is that because Mr. Bennet has no son, the estate must be left to the next male in line, who is a cousin.
The entailment is not something that was automatic under English law. Estates could be left to daughters, and were, unless some owner wrote the entailment into a deed or will.
Since Rosings is not entailed, Anne de Bourgh is able to inherit the estate. Her situation provides an interesting counterpoise to that of the Bennet girls.
Mr Darcy, Elizabeth Bennet, Jane Bennet, Mary Bennet, Kitty Bennet, Lydia Bennet, Mrs. Bennet, Mr. Bennet, Mr. Bingley, Bingley Sisters, Charlotte Lucas, Mr. Collins, Mr. Wickham, The Gardiners, Lady Catherine De Bourgh, Miss De Bourgh, Etc.
Mr Bennet shoked Mrs Bennet when Mr Collins asked for marrying their daughter. The latter did not accept and Mr Bennet said nothing. In fact he liked her decison. And this made Mrs Bennet angry with him because her aim was to make her daughters marry whoever asks for them.
Mr. Bennet had some kind of limitation on his ability to will his estate to his family; Austen says that Mr. Bennet's property may only be inherited by a mal. After Mr. Bennet's death his land will go to Mr. Collins, his closest male relative.
Mrs. Bennet wanted Mr. Bennet to take the family to Brighton.
