Hi Ace you're very welcome. I love mysteries and family history!
I found a thread here on this forum which would be worth reading. An important thing to remember is that there may be somebody of your mother's generation out there who knows something about your own grandfather through family memories.https://polishforums.com/genealogy/relatives-served-armoured-division-gen-maczek-7733/
1st Battalion Polish Rifles under General Maczek were stationed in the parish church of the village of Menstrie which is 15km from Dunblane. The article I came across stated that sadly 'we have little in the way of names of the troops who were stationed here'. That surprises me as I thought the MOD would have records (they definitely have records for the Polish forces in Britain) but in any case, the problem is that even if you find his unit, how would you know which soldier he was? However, in any case you can get a sense of who he was by reading as much as possible about the Polish forces in Scotland, gathering photos, background information, it'll give you a sense of connection to him. Here's another very interesting article:
I found this little gem on a Scottish chat forum:
'.........at a Polish Army dance in Dunblane in 1946, and I had a rare time. The reason I was there was because the Poles had invited the youth-hostellers from the local hostel... I think they were more interested in the female hostellers rather than the hairy-legged cyclists, but hey... can't blame them for that now can we.'
A visit to the village of Dunblane would be well worthwhile, some of the older people there, who were children or teenagers during the war might just have some little memory that could point you in the right direction. Also check out the local library and county library archives for any newspaper articles or things of that kind. You never know what might come up. Photos from a Polish dance for example might give names of the couples photographed, who knows, it's worth a try. At least you can place their romance in the spring/summer of 1942 so that narrows it down a bit.
Finally I found this book, looks nice:
