# Viscount Molesworth

Viscount Molesworth, of Swords in the County of Dublin, is a title in the Peerage of Ireland. It was created in 1716 for Robert Molesworth. He was made Lord Molesworth, Baron of Philipstown, of King's County, at the same time, also in the Peerage of Ireland. Molesworth had been invested as member of the Irish Privy Council in 1697, represented Camelford, Lostwithiel, East Retford and Mitchell in the British House of Commons and served as British Ambassador to Denmark. His elder son, the second Viscount, notably served as Ambassador to the Kingdom of Sardinia, the Grand Duchy of Tuscany and the Republic of Venice. He was succeeded by his younger brother, the third Viscount. He was a Field Marshal in the Army. On the death of his son, the fourth Viscount, this line of the family failed, and the titles passed to the latter's first cousin, the fifth Viscount. He was the eldest son of the Hon. William Molesworth, third son of the first Viscount. His son, the sixth Viscount, was a Major-General in the Army, who was lost in the wreck of Arniston. On his death, this line of the family also failed and the titles were inherited by his second cousin, the seventh Viscount. He was the eldest son of Richard, third son of the Hon. William Molesworth, third son of the first Viscount. He was succeeded by his nephew, the eighth Viscount. As of 2010, the titles are held by the latter's great-grandson, the twelfth Viscount, who succeeded his father in 1997.
Sophie, Duchess of Edinburgh, is a descendant of the 1st Viscount through her grandmother, Margaret Rhys-Jones (née Molesworth; 1904–1985), who was the great-granddaughter of the Rev. John Molesworth, himself the father of Sir Guilford Molesworth and the great-grandson of Robert Molesworth, 1st Viscount Molesworth.
