Julie, Sancti found another birth entry that he has already included on the other post you have for an Elizabeth born in 1942 in Bellshill (the year given on your mother's death cert by your father).
From what you have said elsewhere, you have now ordered their marriage cert. This will let you re confirm her age at the time she married and hopefully provide a parent's name. It should be with you next week if it's already been ordered. Might be an idea to hold off on any more searching until you have received it. You can't move back without verifying information as you go. It is really easy to go off track if you don't check and verify information.
