fee tail male

It was also possible to have "fee tail male", which only sons could inherit, and "fee tail female", which only daughters could inherit; and "fee tail special", which had a further condition of inheritance, usually restricting succession to certain "heirs of the body" and excluding others.

But this domain is under the regime of substitution for a male heir (fee tail male), a rule of succession which she never understood why her husband could do nothing to change, since it clouded his future and that of his daughters, given that she and her husband were unable to have a boy.
