Lancaster 1 ME595 QR-Y 61Sqn.

[Icare9]

ME595 had 8 aboard, including a 2nd pilot, no doubt a new arrival being shown "the ropes".
Not much information on the other casualty.
CWGC shows parents in Kent
BOYD, GEORGE PATRICK. Sergeant (Radio Operator (Air)). Service Number 1290787. Died 15/10/1944. Aged 24.
61 Sqdn. Royal Air Force Volunteer Reserve
Son of George and Edith Elizabeth Boyd, of Sandwich, Kent.
Initially buried at Glentorf Cemetery, reburied 30 May 1947 at Hannover.
Buried at HANOVER WAR CEMETERY. Cemetery reference: Plot 2. Row G. Grave 15.

His birth registered 1st Qtr 1921 (could be late 1920 birth) in Dover, Kent. Mothers Maiden Name: Benn. However I can't find a George P Boyd in 1939 Register, nor can I trace an Edith Elizabeth Benn nor a marriage to a George Boyd.....
Sorry, needs a better brain than mine to find more.

You obviously have the details of F/Eng Webb's murder as detailed in "Footprints on the Sands of Time". Although shot on 19th October and originally buried at Volkenrode, he rests beside his comrade as shown in your photo in Grave 14. Presumably the CWGC had the link between Webb and Boyd due to the War Crimes Tribunal and were therefore able to place them in adjacent graves, a nice touch.
