You wont find a marriage but it might be worth listing their children in date order. This will give you a rough idea of when they married.
If you are wanting to go further back, then the names might help identify their parents names. The Scots often used a traditional naming convention -
1st son - after husband's father
2nd son - after wife's father
3rd son after husband
1st daughter - after wife's mother
2nd daughter - after husband's father
3rd daughter - after wife
other sons and daughters - after siblings
