Not much to chose between both families at this stage. A couple of suggestions. You could look for a birth in 1889 in Coatbridge on
www.scotlandspeople.gov.uk. There are only two showing on SP which are likely to be the ones for the two boys above.
If the date of birth you have for John's birth is correct, then you can verify which is his birth and parents this way. You can also check for a marriage for John to your wife's grandmother (if they married in Scotland) on line at SP. This will include full details on both their parents, including mothers' maiden names, which will help you verify John's details and find the correct family and birth for John.
