Earl of Longford

The title Earl of Longford was first bestowed upon Francis Aungier in 1677. His brother Ambrose Aungier succeeded him and died without an heir. Their niece, Elizabeth Cuffe, married Thomas Pakenham (of Pakenham Hall, County Westmeath) in 1739 and in 1756 he was created Baron Longford. On Thomas' death in 1766 their son, Edward Michael Pakenham, became the 2nd Baron Longford. In 1785 Elizabeth was raised to the rank of Countess of Longford and on her death in 1792 her grandson (who had already acceded to the title of 3rd Baron Longford on the death of his father in 1792) became Thomas Pakenham, 2nd Earl of Longford.
