Hello,
My link with the Woodages is very distant but I have done some research on this huge spread-about family.
It could well be that John Derek's father came from Berkshire initially. I have a couple of George W Woodages on my tree but neither seem to fit the one who married in Wigan.
However, I had a look on the Commonwealth War Graves site and John Derek's parents were living at Maidenhead, it would appear, when the notification was made. So it looks as if they moved back from Lancs to Berks/Oxon
Annoyingly, there were 2 George William Woodages born in that area in 1899. One, I know was born Caversham, son of John Woodage and Mary Ann Wootten.
They were living at White Waltham in 1911. I have this George William married to Ellen Tucker in 1921 with 9 children from 1921-1939. However, I don't have the marriage cert to definitively prove father of George, so I may have the wrong George William.
I don't think so, though, because two of the daughters I have for him, married in Caversham and I have those marriages from the Parish registers.
The other George William was son of George Richard Woodage (son of Abraham) and Grace Blanche Griffiths, but I cannot connect this couple or the father to anyone at present in my tree, alathough I have researched a bit. This George William was bap Caversham St John in 1899. He might be the father of John Derek that you are looking for. [or he might be the one married to Ellen Tucker as above]
The only real way of knowing which the father of John Derek Woodage was is to buy his birth cert which will show his parents, and the marriage cert of the Wigan marriage of George to see who George's father was.
Perhaps a question on the Lancashire board of this site might get you further. A baptism and church record marriage would be useful. A copy of John Derek's Service Record might be also of help if you are able to get it.
Not sure how to go about that for WW2 records.
I hope I have not been too negative.
