Viscount Cullen

Viscount Cullen of Tipperary was a title in the Peerage of Ireland created on 11 August 1642, along with the title Baron Cullen, for Charles Cokayne.

The ancient family of Cokayne had its origins in Ashbourne, Derbyshire. Charles Cokayne High Sheriff of Northamptonshire in 1636, was the son of Sir William Cokayne of Rushton Hall, Northamptonshire, Lord Mayor of London in 1619. The family seat was Rushton Hall.

On the death of the 6th Viscount in 1810, both titles became dormant. Although the issue male of the 1st Viscount thus became extinct, the titles devolved by special remainder, through the female line, upon Albemarle Bertie, 9th Earl of Lindsey, who, however, never claimed them. They became extinct upon the death of Montague Bertie, 12th Earl of Lindsey, in 1938.

Mary Anne Cokayne, daughter of William Cokayne, brother of the fifth Viscount, married William Adams. Their son George Adams changed his name to George Cokayne in 1873 and his son Brien was created Baron Cullen of Ashbourne in 1920.
