Question: Donald Swain Lewis, was a Lieutenant Colonel in the British Army and was the second highest-ranked officer in the Royal Flying Corps/Royal Air Force to be killed in action in the First World War, his father was Ernest Lewis, one of the founding directors of the Army & Navy Stores, was a department store group in which country?
Context: Army & Navy Stores was a department store group in the United Kingdom, which originated as a co-operative society for military officers in the nineteenth century.  The society became a limited company in the 1930s and purchased a number of independent stores during the 1950s and 1960s.  In 1976 the Army and Navy Stores group was acquired by House of Fraser.  From 2005 onwards the remaining Army & Navy stores (the flagship store located on Victoria Street in London and the three others in Maidstone, Camberley, and Chichester) were refurbished and re-branded as House of Fraser stores.  House of Fraser itself was acquired by Icelandic investment company, Baugur Group, in late 2006. Donald Swain Lewis, DSO (5 April 1886 – 10 April 1916) was a Lieutenant Colonel in the British Army and was the second highest-ranked officer in the Royal Flying Corps/Royal Air Force to be killed in action in the First World War.  His father was Ernest Lewis, one of the founding directors of the Army & Navy Stores (United Kingdom). Marshal of the Royal Air Force Cyril Louis Norton Newall, 1st Baron Newall, {'1': ", '2': ", '3': ", '4': "} (15 February 1886 – 30 November 1963) was a senior officer of the British Army and Royal Air Force.  He commanded units of the Royal Flying Corps and Royal Air Force in the First World War, and served as Chief of the Air Staff during the first years of the Second World War.  From 1941 to 1946 he was the Governor-General of New Zealand. Marshal of the Royal Air Force Arthur William Tedder, 1st Baron Tedder, {'1': ", '2': ", '3': ", '4': "} (11 July 1890 – 3 June 1967) was a senior Royal Air Force commander.  He was a pilot and squadron commander in the Royal Flying Corps in the First World War and he went on to serve as a senior officer in the Royal Air Force during the inter-war years when he served in Turkey, Great Britain and the Far East.  During the Second World War, as Air Officer Commanding RAF Middle East Command, Tedder directed air operations in the Mediterranean and North Africa, including the evacuation of Crete and "Operation Crusader" in North Africa.  His bombing tactics became known as the "Tedder Carpet".  Later in the war Tedder took command of Mediterranean Air Command and in that role was closely involved in the planning of the Allied invasion of Sicily and then the Allied invasion of Italy.  When Operation Overlord—the invasion of France—came to be planned, Tedder was appointed Deputy Supreme Commander at Supreme Headquarters Allied Expeditionary Force under General Eisenhower.  After the war he served as Chief of the Air Staff, in which role he advocated increased recruiting in the face of many airmen leaving the service, doubled the size of RAF Fighter Command and implemented arrangements for the Berlin Airlift in 1948.  After the war he held senior positions in business and academia. Air Marshal Sir Arthur "Mary" Coningham, {'1': ", '2': ", '3': ", '4': "} (19 January 1895 – presumably 30 January 1948) was a senior officer in the Royal Air Force.  During the First World War, he was at Gallipoli with the New Zealand Expeditionary Force, was discharged in New Zealand as medically unfit for active service, and journeyed to Britain at his own expense to join the Royal Flying Corps, where he became a flying ace.  Coningham was later a senior Royal Air Force commander during the Second World War, as Air Officer Commanding-in-Chief 2nd Tactical Air Force and subsequently the Air Officer Commanding-in-Chief Flying Training Command. The following is a list of senior Royal Flying Corps generals.  While officially general officers are not considered to belong to any regiment or corps (simply being "late" of their erstwhile regiment), in practice almost all the general officers to hold a Royal Flying Corps-related appointment gained their promotion to the general officer ranks in that appointment and remained in such appointments until the creation of the Royal Air Force on 1 April 1918.  Royal Flying Corps generals then became Royal Air Force generals. Air Chief Marshal Sir James Milne Robb, {'1': ", '2': ", '3': ", '4': "} (26 January 1895 – 18 December 1968) was a senior Royal Air Force commander.  After early service in the First World War with the Northumberland Fusiliers, Robb joined the Royal Flying Corps and became a flying ace credited with seven aerial victories.  He was granted a permanent commission in the Royal Air Force in 1919 and commanded No. 30 Squadron RAF in the Iraqi revolt against the British.  In 1939, Robb travelled to Canada to help establish the Empire Air Training Scheme, a massive training program that provided the Royal Air Force with trained aircrew from Canada, Australia, New Zealand and Southern Rhodesia.  He commanded No. 2 Group RAF of RAF Bomber Command and No. 15 Group RAF of RAF Coastal Command. Royal Air Force Manywells Height (also known as Royal Flying Corps Manywells Height, Royal Flying Corps Cullingworth & Royal Air Force Cullingworth) was a grassed airstrip in use as Home Defence during the First World War.  The site was just south of the village of Cullingworth which is south of Keighley and north west of Bradford in West Yorkshire. Air Vice-Marshal Sir Philip Woolcott Game, (30 March 1876 – 4 February 1961) was a British Royal Air Force commander, who later served as Governor of New South Wales and Commissioner of Police of the Metropolis (London).  Born in Surrey in 1876, Game was educated at Charterhouse School and entered the military at Royal Military Academy Woolwich, gaining his commission in 1895.  Serving with the Royal Artillery, Game saw action in the Second Boer War and the First World War.  After serving with distinction and bravery, Game transferred to the Royal Flying Corps in early 1916 serving as General Trenchard's chief staff officer.  Finishing the War as an acting major-general, Game remained in the Royal Air Force after the close of hostilities.  Notably he served as Air Officer Commanding RAF India and Air Member for Personnel.  He retired from the military in 1929, having reached the rank of air vice-marshal. Archibald Campbell Holms MacLean, {'1': ", '2': ", '3': ", '4': "} (23 October 1883 – 30 April 1970) was an officer in the Royal Scots, Royal Flying Corps and Royal Air Force.  MacLean attended the Royal Military College, Sandhurst, before he was commissioned into the Royal Scots.  He transferred to the Royal Flying Corps in 1913 and during the First World War served as a squadron leader and wing commander before taking up senior training and staff appointments.  In April 1918 he transferred to the newly formed Royal Air Force and was subsequently promoted to brigadier general just after the end of the First World War.
