Robert King had already been created
Baron Erris of Boyle, in the County of Roscommon on 29 December 1800 in the
Peerage of Ireland, and was raised to become
Viscount Lorton, of Boyle, in the County of Roscommon on 28 May 1806. He was elected as an
Irish representative peer in 1823 and was made
Lord Lieutenant of Roscommon between 1831 and 1854, a purely ceremonial honour but an important one. He died on 20 November 1854 at Rockingham Castle. His elder son,
Robert King, 2nd Viscount Lorton, succeeded to the Earldom of Kingston on the death of his cousin in 1869. The titles have remained united ever since. His younger son,
Lawrence (later King-Harman), inherited the Rockingham and Newcastle estates. The Rockingham estate was inherited by
Edward Robert King-Harman, an MP and, earlier in his life, adventurer. His daughter, Frances, married Rt Hon
Sir Thomas Stafford, 1st Baronet, a physician and member of the
Irish Privy Council. Their granddaughter, Joan, Lady Dunn is the representative of the Rockingham branch of the family. The Newcastle estates were inherited by Lawrence's younger son, the ancestor of Tony King-Harman, the historian of the King family referred to above. ==References==
