Hello again,
Yes, I think this must be my grandfather. It was the different names given for his parents that bothered me, but both could be errors of transcription. Especially with the Glendinning name link through the mother's family. So I think I can feel comfortable with that.
That is sad about the WW1 record destruction. I didn't know that. I tried hard to see if there was any archives I could explore on the regimental website without success. I wanted to see if he had served in France and to try to find out if the condition (pneumonia and pulmonary embolism), was trench warfare related. Yes, once I realised he had not died in Scotland, I was able to find those details, which solved yet another mystery for me. I wish I had known where his grave was when I was down that way a couple of years ago. As I said, Unfortunately, English death certificates (and other documents) are much less detailed and one can't see those images online.
Thank you for all your help. You have given me some very useful tips and I have learned a lot.
Regards, Mundell
