Thank you so much for the information. I really appreciate your time.
Hello Monica,
Thank you for the post. I will take a look at the 1861 census (I never thought about that,

)
On the marriage cert there is not any other information beside the parents names for Mary.
A mistake on my part,thank you for pointing this out. I never thought to link the topics. It was mentioned that Mc Aulay is an Irish surname so with this in mind I came across the post as I wasn't having much luck finding her in Scotland.
This is a good point Monica.

The marriage is listed as a statutory marriage. This is something I never knew. I have managed to find a lot of information about Biddy and her family who moved Kirkintilloch to Govan. However,I haven't found anything to say that she was with her her parents. I have being trying to find something about Mary's age but i don't really have anything to get a better idea.
I also already have the death cert for her husband Cornelius and that only says he was married to Mary Kilday.

I have attached the Marriage cert.
