Thank you so much everyone...Have only just seen your replies.
What I meant was that Frances' name was written as Francis, incorrectly, I assume. Her maiden name is written as Beattie, like the snippet shows.
John Clark, on the marriage of Mary Ann is mentioned as a Clerk, yet on the further doc it says he is a Police Clerk.
We, (My cousin and I) have found an 1871 Scottish census, with a Mary Ann Clark from Ireland and her mother Fanny Clark also from Ireland, living in the home of Margaret Moodie, Mary Ann's sister. Margaret is married to Robert Moodie. They live at Quoad Sacra Parish of Martyrs. They have a daughter named Frances Moodie, which gave us the thought that maybe she was named after her Gran. I have purchased the Scottish certs of Frances Moodie's birth and Margaret and Roberts marriage but there were a couple of question marks arisen. 1. John's job is a clothier, not a police clerk and 2. Frances has now got the maiden surname of McKay, spelt Mackie and has lost the Beattie. Today however, we noted that John is deceased on Margaret's doc but not on Mary Ann's. It can't be the same person if he was deceased because Margaret's wedding was in Neilston, Renfrew 1864.
I have been told by Scottish People website that documents had errors on alot, where maiden surnames were different, but I'm thinking, due to the other differences, it can't be the same people?
Thank you for looking for me.
