Hereditary title

The House of Lords is the upper legislature of the Parliament of the United Kingdom and is filled with members that are selected from the nobility (both hereditary titleholders and those ennobled only for their individual lives).

Hereditary titles, in a general sense, are nobility titles, positions or styles that are hereditary and thus tend or are bound to remain in particular families.

Often a hereditary title is inherited only by the legitimate, eldest son of the original grantee or that son's male heir according to masculine primogeniture.
