Thank you Sue. The differences in height, eye colour etc. could mean they are not the same man and I still have the problem of not being able to tie him back to a birth mother.
I have been unable to find a birth for Willesden William in 1900 though he is recorded as an adopted son on 1921 Garston census!
One thing leads to another

I think this may be one ancestor I will only be able to speculate about.
Thank you everyone for your time and help
