I think the following is all we have to go on. According to the Dutch researcher:
One of the crew members was thus Flight Officer George Roland Wright (Navigator), service number: 148758.
George (born 1908) was the son of Thomas Edgar and Ethel Mary Wright from Undercliffe Street, Bradford.
As far as I know George had 2 brothers and 1 sister (1 brother was called Donald, 1 brother was called Thomas and his sister was called Winifred Margaret).
George was the husband of Mary Wright (nee Driver) and they were married on July or August, 1938 at Eccleshill Parish Church in Bradford.
George lived on Undercliffe Street in Bradford until his marriage.
Mary Driver lived at West View, Undercliffe until she married George.
Here, however, my search for information regarding George falters.
George joined the Auxiliary Airforce in 1938 (so he is unlikely to be on the 1939 register, because I heard military personnel were not recorded on this register).
I did, however, obtain information from a contact in Bradford that George most likely lived after 1938 at “Undercliffe”, Russell Bank Road, Four Oaks, Sutton Coldfield. This address was mentioned on a probate from George. (Undercliffe is the name of an area of Bradford where George grew up. My contact in Bradford discovered that the houses at Russell Bank Road all have names and one was/is called “Undercliffe”. It looks like he possibly named his house after the area he’d grown up in).
It looks from this that there is little doubt about the Sutton Coldfield connection. And possibly that George was RAFVR - one of those who volunteered before the war for aircrew training in their spare time and were brought into use when they were needed. It's either a remarkable coincidence that Mary's brother was also RAF aircrew - or, more likely, he and George were mates together prewar in the RAFVR. And it is starting to look as though George and Mary's time in Sutton might well have been brief.
What multiple tragedies befell some unfortunate families in those dreadful days.
