I am trying to find where my cousin F/S George Clark Mitchell (189118) trained for the RAF. He was in the RAFVR and then ended up in 103 Squadron at Elsham Wolds as Air Bomber on Lancaster NE136 which was shot down by night fighters on 14 July 1944, the crews 27th operation. The Lancaster crashed near Biencourt-Sur-Orge and all the crew were lost.
He started his tour on 15 Mar 1944 but I cannot find where/when he enlisted or where he trained before joining 103 Squadron.
Can anyone suggest where I might search please - I just can't seem to find any relevant records.
