Baron Willoughby of Parham

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.

[1] An error in identifying the heir in 1680 resulted in an inadvertent novel creation by writ in 1680, without the restriction on inheritance by gender.

[8] No action was taken at the time, but on the death of the 15th Baron in 1765, Colonel Willoughby renewed his claim, and it was formally recognized in 1767.

Their son was Charles, Lord Willoughby, who married Margaret, daughter of Edward Clinton, 1st Earl of Lincoln.

[13] This family tree includes only Barons Willoughby of Parham and their descendants who are relevant to the succession.
