International quest to find photo of Tottenham Lancaster Bomber crewman who died in 1944 crash

An appeal has been launched by a group in Belgium who are wanting to put up a memorial to the crew of a Lancaster Bomber that crashed in Belgium 1944.

The navigator on that flight was related to Deborah Hedgecock the Curator of Bruce Castle Museum; Howard Hedgecock survived the crash but was captured as a PoW. He survived the camps and came home, going on to get married and having a family. Sadly not all crew members survived – four died.

The Belgian village - near where the crash-site was - wish to set up the memorial to all the crew and have gone about tracking down photographs of the crew for the memorial.

Tracking down much about one of the crew is proving very difficult. Reginald Ivor Harvard Davies (known as Ivor), at one point lived with his family lived in Grand Parade on Green Lanes, Harringay.

It's a very long-shot, but does anyone know the family or even have a photograph of Ivor?.

Below is some background.

Reginald Ivor Havard Davies, (Service Number: 156998, RAFVR), was an air gunner. He and his fellow aircrew took off in Lancaster III ND745 of 115 Squadron, at 22:59 hours on 23 May 1944 from RAF Witchford in Cambridgeshire, for an operation against Dortmund in Germany. 

After the mission, the homeward-bound aircraft was intercepted and shot down. The plane crashed in Zondereigen. Three crewmen bailed out, but were captured and became prisoners-of-war; the remaining four, including Ivor, perished in or just before the crash.

Prior to joining the RAF, Reginald Ivor Howard Davies was a CID Detective Sergeant with the Metropolitan Police (T Division, Hammersmith; warrant number 117663), which he joined on 4 June 1928. 

Ivor was born on 18 August 1903 in Bowes Park, Edmonton, Middlesex to were John Havard Davies (1868–1955) and Maria Jane Gilbert ( b1860). In the 1911 census, he was living at 69b Grand Parade, with his mother and two siblings. His father remarried in in 1922 to Harriett Gertrude Batey, and in September 1939 they were still living at 69b Grand Parade.

Ivor married Helen Maud Palmer (1904–1989) on 19th January 1929 in Harringay (he had been living at 69b Grand Parade). In September 1939, they were living at 138 High Street, Teddington. Helen remarried after Ivor died.

The family haven’t found any children for Ivor, and his widow’s children from a subsequent marriage haven’t found any photos.

Can you help?
