Thanks Gordon,
The marriage was on 1st august 1930, "after Banns according to the forms of the Chruch of Scotland". There are lots of marriages in my family that take place at a manse rather than a church, so I am not surprised at all at that - I just couldn't find any mention of that church. Thanks for tracking it down for me. I think I can now confidently add "Allars Manse" to my list of places.
Cheers,
Clare
