Hercules Langford Rowley PC ( – 25 March 1794) was an Irish politician and landowner.
Early life Rowley was born . He was the only son of Frances (née Upton) Rowley and Hercules Rowley, a Member of Parliament for County Londonderry from 1703 until his death in 1742.
His father was the only son of Sir John Rowley (who was knighted for his services at the time of the Restoration) and the former Mary Langford (eldest daughter and heiress of Sir Hercules Langford, 1st Baronet). In 1661, his great-grandfather Langford bought Lynch's Castle (located on the Sumerhill demesne in County Meath) and many other townlands from The Rt Rev. Dr. Henry Jones, the Lord Bishop of Meath. His aunt, Lettice Rowley, was the wife of Arthur Loftus, 3rd Viscount Loftus. She was succeeded by her son, the second Viscount.
Rowley inherited his father's estates, including Lynch's Castle, which had been occupied by the Langfords since 1661. In 1731, Rowley hired architects Sir Edward Lovett Pearce and Richard Cassels to build him a new Georgian mansion on the property, known as Summerhill House. Lynch's Castle was abandoned in the 1730s but remained on the land as a folly. Summerhill House was damaged by fire on a number of occasions before it was set on fire by the Irish Republican Army and completely destroyed in early 1921, remaining a ruin until it was totally demolished in 1970.
In 1743, upon entering parliament, Rowley purchased a large house on then fashionable Mary Street in the North of Dublin city. The house was later to become known as Langford House and was an imposing 5-bay, four-storey over basement structure.
