Captain Maxwell Fox was born in 1826, the son of Major Barry Fox and Sophy Fox of Longford. Fox was educated at Eton, and subsequently entered the Royal Navy. He served under Commodore Lambert on board the battleship, Serpent at the bombardment of Rangoon in the Burma War of 1853, for which he was awarded a gold medal. He retired with the rank of captain in 1864, a year after his father’s death, and returned to Ireland to manage his estates, and assumed residence at Annaghmore House.
Fox married Florence Jane, eldest daughter of Sir Andrew Buchanan, Bart. Following her death in 1882, he married secondly in 1886, Edith Edgeworth of Kilshrewly, eldest daughter of Rev. Essex Edgeworth. He served on the visiting committee of Tullamore gaol, and as an ex-officio guardian of the Tullamore Workhouse. In 1868 he assumed the office of High Sheriff. Maxwell Fox sold up his own farm in 1896, prior to his departure from Annaghmore, and died suddenly at Foxhall, County Longford on 14 September 1899.

Middleton Westenra Biddulph was born on 17 August 1849 at Rathrobin, Mountbolus, King’s County (Offaly). He was one of six children, and the eldest surviving son of Francis Marsh Biddulph (1802–1868) and Lucy Bickerstaff (d. 1896). She was born in Preston, Lancashire and they married in 1845. The Bickerstaff connection was to be an important one for the surviving sons of Francis Marsh Biddulph, and led to a substantial inheritance in the 1890s for Middleton W Biddulph, and his brother Assheton, who lived at Moneyguyneen, Kinnitty.
The Biddulph ancestors were from Staffordshire, and later Wexford, and had arrived in King’s County from as early as 1694 or 1660. Lt Col. Biddulph held about 1,000 acres, of which perhaps 600 to 700 acres he farmed with the balance leased to his long-standing Protestant tenants. His landholding was principally in the townlands of Rathrobin and those adjoining of Clonseer, Cormeen, Kilmore and Mullaghcrohy, all near Mountbolus, in the civil parish of Killoughy and the barony of Ballyboy.

Middleton Biddulph went to Foxcroft House boarding school in Portarlington, aged 11, thereafter to the Royal School in Banagher, and joined the army when he was eighteen, enlisting with the Northumberland Fusiliers (Fifth Regiment). Initially an ensign or cornet, he rose in the ranks quickly and was a Lieutenant by 1871, Captain in 1881 and Major from 1885. Before retirement in 1896 he held the rank of Lieutenant Colonel. He spoke French, German and Hindustani and stations included: Hythe March (1872), St Helier’s, Chatham (1879) Portsmouth (1881), Agra (1880), Mullingar (1882), Newcastle (1886), Colchester (1887) and Aldershot (1891). It was while he was at Mullingar with the Ist Batt. Northumberland Fusiliers that he was appointed adjutant of the Ist Northumberland and ordered to proceed to Alnwick. It appears that he met his future wife, Vera Flower, following on from an introduction by her brother Stanley Smyth Flower (1871–1946), who was also an officer in the Royal Northumberland Fusiliers. They married in 1891. Vera Josephine Flower was a daughter of Sir William Flower, Director of the British Museum of Natural History, South Kensington, London. They did not have children.

When Biddulph retired from the army in the mid-1890s, he returned to Rathrobin and rebuilt the old house with the benefit of the Bickerstaff inheritance over the period 1898 to 1900. He employed Sir Thomas Drew as architect and William Beckett of Dublin as the builder. Once the new Rathrobin House was completed, Lt Col. Middleton Biddulph got on with his duties as a landlord and was a regular attender at the Petty Sessions, the Board of Guardians, and the County Infirmary, served as High Sheriff in 1901, and was appointed Deputy Lieutenant of the County in 1910. He was also on the board of the King’s County Joint Committee for Technical Instruction and the King’s County Farming Society. He and his wife left for England in June 1921 as the military campaign of the IRA in the locality intensified, and Rathrobin House was destroyed by Republican IRA forces in April 1923. While he seemed to have planned to return to Ireland after this, an attack on his land agent, Violet Magan, and his own declining health delayed plans to do so, and he died in Chelsea in May 1926.
