Looking for records applicable to father's relations named KIRKHAM

Question

Am looking for any BMD records for 4 children - 3G1B - relations of my father [hence me!]. Mother was Elizabeth ("Beth") Potts Duncan, father Ian Kirkham, they married in 1946. All family connections are Scottish. No search results on ScotlandsPeople or any other site that I am using. Girls had unusual christian names - Yronnie, Mhairi and Sheena. No idea if anyone in this tree is still alive or not, hence the searches for my aging father

Comments

Marriage of Beth Duncan to Ian Kirkham was in January 1946 in Gourock. (Most of my past family were from the Gourock, Greenock, Largs, laterally Glasgow areas) Beth had a sister, Mervyn, and her mother was Jessie Brown, father Sam Duncan, Beth herself born in 1923. Re-reading my father's notes, there were 4G 1B - other sister was called Ruth and the brother was Ross (? Father not 100% positive on this)

Answer 1

Do you have any details you can add (however sketchy) about where and when these people were born, or lived? Where did the 1946 marriage take place? Anything you can add to your question (and as tags) will help people to find you answers.
