Thank you all for your recent posts. Absolutely fascinating and great detective work going on - there's the feeling of an impending breakthrough.
But to be honest, I'm finding it a bit confusing.
1. Is there a detectable connection between the Albert Wilson in 171 Camden that Sc00p found with the amended birth date?
Still can't understand how or why such a change could be made. and the Albert Sydney Spiers in the Queen's Hotel in Birmingham and Sc00p find of Albert Spiers recorded as in the Navy?
2. Jumping ship - if not court martialled or prosecuted at the time - might be a reason to change name, ditto if your Father was accused of Murder, but why isn't it also an issue in the 1920s when potentially working at the Queen's Hotel?
3. If we're on the right track with this/these Spiers, am I correct that for at least Sydney a previous marriage might have occurred but no divorce? If he is the right chap, is that the reason he never married Madge and subsequently adopted Wilson?
4. I haven't yet found a death cert for this Albert Sydney. Does this lend weight to the connection with Madge - because Albert Sydney's death might have been our recorded Wilson in 1943?
5. Also bear in mind that for Madge 'Well to do'' would have meant anyone who wasn't from a background of the abject poverty in which she was brought up.
6. I have been following up on the LMS link and have been referred back to the National Railway museum - who I wrote to 3 weeks ago - as a potential start point.
7. The Queens Hotel was adjacent to New Street Station - a substantial building (see photo) the connection with Albert as a waiter and LMS - or at least being well positioned to seek employment with the railways is compelling.
8. It would be perfect if there was a record of Madge working there about the same time - but I have a feeling it won't be that easy.

9. any sign of Albert Sydney on the 1939 Register? I still don't understand how 'Alf Wilson' managed with out an ID/Ration card during the war without registering in some way.
