Peerage of England
The ranks of the English peerage are, in descending order, Duke, Marquess, Earl, Viscount, and Baron. While most newer English peerages descend only in the male line, many of the older ones (particularly older baronies) can descend through females. Under English inheritance law all daughters are co-heirs, so many older English peerage titles have fallen into abeyance between various female co-heirs.
Baron Willoughby of Parham
Baron Willoughby of Parham was a title in the Peerage of England with two creations. The first creation was for Sir William Willoughby who was raised to the peerage under letters patent in 1547, with the remainder to his heirs male of body. The second creation was by writ in 1679, without the restriction on inheritance by gender. The creation of the barony gave right to an hereditary peerage and seat in the House of Lords, the upper house of Parliament.
