A group of World War II enthusiasts are seeking the family of a sergeant who died in a bomber crash for the unveiling of a memorial plaque.

Sergeant Raymond Stanley Lang, 32, from Streatham, died when the Lancaster bomber carrying seven crew, in which he was a mid-upper gunner, crashed into a river bank near Kessel, Holland, in 1944.

The Lancaster left RAF Mepal, Cambridgeshire, to bomb the Fischer Tropsch oil refinery and aviation fuel producer in Homberg, Germany, with a full load of bombs on July 21. It was attacked by a German fighter over Limburg, Holland, and crashed near Kessel.

Now Barrie Davies, a Briton living near Kessel, Denise Boneham, who lives in the UK, and other WWII enthusiasts are planning to unveil a memorial plaque in Kessel to mark 67 years since the crash.

They want to find members of Sgt Lang’s family to attend the unveiling of the plaque on July 22.

Sgt Lang married Edith King in Paddington in 1940 and they lived together in Streatham, but had no children.

Ms Boneham hopes his widow married again and they may be able to trace her children.

She said: “We hope we can find a member of his family to attend. We have found members of other sergeants’ families who will attend and we would like to find Sgt Lang’s relatives as well.”
