Just found this too concerning one of the crew:

Harry Edwin Hastings, Flying Officer, 189139, Royal Air Force. Harry was the son of Edwin and Emily Clara Hastings of Highnam's Park, Essex. He served with 36 Squadron, Royal Air Force, which was a Coastal Command unit, equipped with the Vickers Wellington, which flew from RAF Chivenor in an anti-submarine role. Harry had served with the squadron in the Middle East before it moved to Chivenor in 1944, and he had got engaged to Marie Lloyd, of Bush Row, Haverfordwest. On 24 January 1945 Harry was on patrol in his Wellington when it was lost at sea. He was 23 years old, and is commemorated on the Runnymede Memorial, Surrey.

Assuming they were flying a Wellington GR Mark XIV, the Maritime version of B Mark X with a chin radome housing the ASV Mark III radar and added RP-3 explosive rocket rails to the wings, all that is needed is to sort through the 841 aircraft built at Weybridge, Chester and Blackpool to find one that was lost on 24-1-45.
