Plan of attack:
Firstly

You need to see the original marriage records as witnesses names may help.

Look for any other wills -  don't forget possible maternal sides.

The baptisms ( Mitten, etc) do not seem to be online. You need a map of parishes and chapels which cover the relevant places and look for the ones which are not online, working out from the Blunham area. Genuki for the relevant counties should help with this. Hopefully the records should be with the county record offices.

Have you considered taking a DNA test?

Old newspapers?

Local history books?  Has anyone else researched them?

I can't think of anything else to try. May be very hard and take a while to get anywhere.

Good luck.

I was browsing in a book shop today, and was very tempted by this book, as Ray Bailey was born in Co Durham (though as far as I know not related to me, although I have Walkers in my extended family!)The family later moved to Luton for work.

This must be his birth registration
March 1919

Bailey    Raymond    Walker    Chester-le-S.    10a   841

In 1921 he and his parents William & Margaret are with Walker grandparents .

Did they have a registry office wedding?

I would have expected them to have a buttonhole flower or corsage if it was a wedding. Perhaps it is the engagement?

It is difficult to see the details but there could be the ends of multiple cantilevered joists showing under the jetty of the small triangular half timbered feature. It could therefore be a medieval timber frame building from the 1600's with some later additions.

This page has a reference to a house dated 1600 in the High Street

I wouldn't dismiss the army connection too quickly. The army is the most likely place that a boy from a poor family would receive musical training.
There is no obvious Brighton birth registration of a Charles Vine around 1855 and the 1871 census return would not be completed by Charles.
It may be worth asking if he attended Kneller Hall.
