I was wondering if anyone knows of a farm possibly in the stirling area called something like primrose farm? Operating around the 1930's?
Jojo, you need to get hold of a few solid facts, as what you have said so far is rather vague.
If you are sure the farm was in either the county or parish of Stirling, it can't be Rosyth which is not even the next county (Clackmannanshire lying in between) let alone a neighbouring parish.
What is the surname of the family who you think were living there, and do you have any of their given names? (Be careful not to to reveal information about anyone who is or may still be living, as that isn't allowed on RootsChat).
If you have names and dates, you could check the birth and death indexes on Scotland's People to find out which registration district they lived in, which will narrow your search considerably.
Once you know the district, you can search (or get someone else to search for you) the valuation rolls and registers of electors from the 1930s.
