The big breakthroughs are always exciting aren't they

I am excited for you, and it is not my family!
Some thoughts for you to progress through on details:
The NAS (the National Archives of Scotland now merged and is being renamed the National Records of Scotland) details provided by Hume:
Reference CS258/11465 in 1945
Title Mary E Gray or Blair v Robert H Blair - Divorce
Reference CS46/1964/732 in 1964
Title Mary Gray or Buchanan: Appointment as Trustees under Feu Disposition by Rob Thomson of Rev John B Mackenzie & others (Polmont Domestic Mission)
You can contact them (email enquiries[replace with 'at' sign]nas.gov.uk) and ask them for a quote to photocopy these documents and send them to you via 'snail mail'.
The other route, need to do more homework on this, is to check on the voter's roll to see who lived at Burnside Cottage between at least 1920-45, maybe more years either side. This seems to be where all the family women lived! These searches cannot be done online though but likely a main local family history library would have the voter roll ledgers to check (this is where the homework is needed as to which one!). Again, this is likely to require some emailing direct to the relevant library for to ask for help (unless a family member...or RootsChatter...lives nearby

).
