Hi Luc
Unless you are fortunate enough that someone recognizes John from their own family tree, it will be hard for people to help out because his birth is likely to be outside the cut off point for on line search for births on Scotlands People (1906).
If you get not response from this post, can I suggest that you take a step back and order his marriage cert. This will include his father's name and John's age. This will help you then look for his birth in Scotland with more precise info. You will have to order details of his birth from the GROS, have a look at this link:
www.rootschat.com/forum/index.php/topic,193879.0.htmlThe only death in West Lothian for a male Wallace in 1953 is showing as this one:
1953 WALLACE ALEXANDER 83 UPHALL /WEST LOTHIAN 672/00 0179
If you are confident of your dates for John's father's death and also the county as West Lothian, then this could well be his death entry. Original images of certificates are available on the pay to view site of Scotlands People
www.scotlandspeople.gov.uk. Charges are v. reasonable (£1.20 to search and view BMD images). If you haven't seen any Scottish certs. before, they are very informative and will include this Alexander's wife, including her maiden name, and also his parents' names and who reported the death. It will also show last residence which might tie up with the address you have.
Regards.
