A review of the Operational Records Book (ORB) for 201 Squadron reveals the flying history of the 11 men.
F/O Guy Nelson WILKINSON 51121 was posted in to 201 Squadron with effect from 3 August 1943.
F/Lt Charles Seymour GROSSEY 45199 Appears to have been posted to 201 Squadron in June 1943
F/Lt Arthur Charles GRIFFIN 62311 Was posted in to 201 Squadron with effect from 3 August 1943
F/Sgt Norman Baron PICKFORD 657043 can be found in the ORB from at least Sept 1942, earlier than that, only men of Warrent Officer rank and upwards are recorded.
F/Sgt Joseph William BURTON 1287499 His name appears on just one other operational flight on August 17th in the ORB, so this tragic mission was possibly only his second sortie with the squadron
F/Sgt John Robert COSTER 1259732 + F/Sgt Coster's name can be found in the ORB from at least November 1942.
F/Sgt Walter Noel PITTS 749904 + F/Sgt Pitt's name can be found in the ORB from at least November 1942.

F/Sgt William MCLEAN 996639 F/Sgt Mclean's name can be found in the ORB from at least Feb 1943.

The core of the crew had thus come together during the summer of 1943 and flown a number of missions under the command of F/Lt Grossey, however, it is worth noting that crews swapped and changed quite a bit in 201 Squadron.

CWGC records F/Lt Grossey was the husband of Adelaide Lily Ann Grossey, of Kidlington, Oxfordshire.  The couple had married in 1938 in London.  His mother lived in St Pancreas, London during the war so the connection to Kidlington is unclear since his wife's family also were from London. His brother Raymond was missing in Action since 1939 flying with the RAF. Their parents were Charles and Louise Grossey.  They had two other brothers, Dennis who served with the RAF during and after the war, and Ralph who was a Royal Navy officer.  It has proven impossible to find a photo of Charles Grossey despite a number of contacts being made with family relatives.

Arthur Charles Griffin 62311 was the son of Charles and Emma Griffin of 27 Queen Street, Leighton Buzzard.  He had been an employee of the of the I & R Morley Ltd. clothing company according to the book, The Secrets of Q Central: How Leighton Buzzard Shortened the Second World War by Paul Brown and Edward Herbert.

The family of F/O Guy Nelson WILKINSON 51121 were instrumental in efforts to remember this crew.  His daughter Maureen and her husband Les Ingram travelled to Ireland to visit his grave and reached out to try and contact families of the other airmen.

F/Sgt Norman Baron PICKFORD 657043, Navigator lived at Maythorne, 90 Holmfield Road, Leicester and formerly off 'Broadholme', Manor Rd, Leicester. He was the son of Edith and James Pickford.  His mother had passed away shortly after he was born.  His entry on the calendar of wills for 1944 records him as "PICKFORD, Norman Baron  otherwise Norman otherwise Norman Byron of Maythorne 90 Holmfield-road LEIESTER died 22 August 1943 on war service".

George William Davies 996539, one of the survivors gave his next of kin and address as his wife at 116 Kensington Road, South-end of Sea, Essex.

His family were able to provide this scan of his log book, which rather understates events as many wartime documents do.  It is noted that he had flown mostly that month with F/O E F H Bent J5910, had been posted into 201 Squadron only in July 1943.  His log book earlier confirms his posting to 201 Squadron in February 1943.

Sgt Davies was no stranger to the dangers of war time flying having survived the crash of 120 DQuadron Liberator AL519 on 3rd November 1942.  That aircraft had taken off from Ballykelly on night flying training when it crashed into Benevenagh mountain near the airfield.  The pilot was killed but the remaining crew survived.

Sgt William McLean 996639 had an address at Alwinton, Harbottle, Morpeth in Northumberland recorded by the Irish Army and had had an already busy wartime career.  He had already served a tour of duty with Bomber Command's, 7 Squadron on Stirling bombers.  On the night of 6 Dec 1942, his aircraft, Stirling R9259 was shot down over France.  Of the crew of seven, six lost their lives with only Sgt McLean managing to escape the aircraft and then evaded capture and escaped through Belgium to neutral Spain and thereafter making his way back to England.  AS can be seen above from the 201 Squadron ORB, he back in service with Coastal Command in February 1943.

Les Ingram provided the following information about Sgt Mclean.  Sergeant W McLean was recommended for the DFM by his squadron commander, Wing Commander O R Donaldson, in a letter dated 24 January 1943 (PRO AIR2/4947 2449) - 'Whilst over the target the aircraft was hit by anti-aircraft fire and the rear turrett (sic) was put out of action. Sergeant Mc.Lean made his turret function under manual control and when the aircraft was later attacked by a night fighter, his conduct, courage, determination and devotion to duty were of the highest order under very harassing circumstances'. Despite this statement the recipient, in a letter dated 19 October 1980, regarded the award of his decoration as being due to his succesful 'evasion' and escape from German occupied Europe following the destruction of his aircraft. His letter states: 'We were returning from a raid..in a Stirling of No.7 Squadron, in which I was a rear gunner. When over Belgium the aircraft had a direct hit in the port wing, and burst into flames. The aircraft started to go down, and pieces of wing was (sic) breaking off. I could get no contact with my skipper, so I decided to bale out. I managed to get out with difficulty as the aircraft was going straight down, and I landed in a ploughed field. I managed to evade capture by hiding for several days until the search for the survivors of the aircraft crash by the German army had been called off. After 5 days I went to a remote farm and the farmer gave me a civilian suit of clothes, and put me in touch with an escape organization. From then on I travelled to Brussels, Paris, Bayonne. I then walked over the mountains into Spain, and contacted the British Consul in San Sebastian. From then on I went by road to Madrid, Saville (sic) and by ship to Gibraltar, and back to England by air. I was the only survivor of the crew....I was awarded the DFM for escaping from Germany in 1942'.
It is understood William was born in Morpeth in 1912 and passed away in 1988 in Northumberland.

If you can provide any help in finding relatives of the crew members listed above with no photos I would be most grateful.

The photo below was published in a post war newspaper, likely in the 1990's, the date is to be confirmed.  It shows the white painted tail of the aircraft.

The following photos were taken during a hike up the slope of Slieveglass in July 2007. They show some of the remains of Sunderland DD848 which lie on the mountain side. All four Pegasus engines can be found in the heather.
