Hi Diddy,
Ooops typo re Malcolm Balmain date of death and to my shame I did preview the post before submitting it

Malcolm had four children that I am aware of but have no deaths etc recorded for.
Based on the marriages I am assuming his first two wives possibly died in childbirth which could account for the two unnamed deaths of his children.
Issue I have:
John 04 apr 1713 - went onto marry Margaret Duncan
George 11 May 1719 - nothing further
John 09 Apri 1724 - went onto marry Alison Wilson
Katherine 23 Jun 1726 - went onto marry James Hendry
I have a question mark over a possible son, David born 23 Oct 1692 in Orwell Kinross, mother unknown and no record of a marriage but could indicate an earlier date of birth than I guesstimated

.
A Malcolme Balmain was born in 1662 circa to a Malcom Balmain in Dunbarney, further data unknown but there seems to be a strong Balmain/Balmane connection to this area in the early 1600's, with family christian names; William, Alexander and Malcolme.
Problem is of course finding out if any link to my Malcolm.
I have managed to collate a list of Balmain births and marriages for most of this area in Scotland, which will be a handy reference once I have firmed up the earlier relationships - am very happy to assist anyone by the way with this data

I am certainly leaning towards Walter being his brother though.
Huge thanks,
Debs
