William Widdrington, 4th Baron Widdrington

William Widdrington, 4th Baron Widdrington (167819 April 1743) was an English peer who was stripped of his titles by the Crown for being involved in the Jacobite rising of 1715. but was reprieved after an intervention by his wife, Catherine Graham.

Although his title and estates were forfeited, he was not executed Jane died in 1714, and in 1718 he married Catherine Graham, the daughter of Richard Graham, 1st Viscount Preston. In 1739, Catherine and her sister Mary inherited the estate at Nunnington Hall, Yorkshire, from their nephew Charles, third and last Viscount Preston, who died without issue.

After Widdrington's death on 19 April 1743, he was interred in his wife's family vault at Nunnington parish church. A memorial tablet was erected, commemorating his life and virtues; it refers to his part in the Jacobite rising by speaking obliquely of 'the affair at Preston'. When his son Henry Francis Widdrington, who claimed the barony, died in September 1774, this branch of the family appears to have become extinct.

His brother Peregrine and sister-in-law Maria, Duchess of Norfolk, were both staunch Jacobites as well.
