Does any member know if nominal rolls were kept of volunteers/conscripts of the Royal Scots during WW1? The reason being, I have been given a family photo of a soldier dated 1917, it looks like my grandfather who lived in Edinburgh. As far as I knew he wasn't called up, but this photo proves otherwise.
Have you looked at the online family history sites such as Findmypast or Ancestry as these have many of the surviving WW1 soldier's service records?
Contacting the Regimental Museum: Museum | The Royal Scots may be able to give you some pointers either way and there is a link offering guidance on individual research at: 1st World War | The Royal Scots (Afternote - apologies - link seems currently unavailable) Any indicators on your photo of which battalion (from 35) or Theatre? Mine was arguably easier by being in one of the ‘Dandy Ninth’ (kilted) fractions.
I've emailed The Royal Scots museum, awaiting a reply. In the photo of my Grandad, the buttons were indistinguishable, but he lived in Edinburgh so no doubt he will have joined the Royal Scots. His brother was in 5th Bn. Royal Scots, but was kia at Gallipoli in 1915. I have also tried a family history site, they said that most records were lost during the 'blitz' WW2, and they couldn't help.
That is partly true but there are a lot of service records on the sites and, if lucky, they will give other personal details to confirm 100% if they are the correct records or not. The sites also have the Medal Index Cards and Award Rolls but these will only give name and number so it will be a guess if it is the correct man. Worth a go for his service records in my opinion. Soldiers were sent to whatever regiment the Army required, possible but not necessarily the Royal Scots.
I'll try a different site and maybe get lucky. I have checked out the Medal Index Cards, 2 turned up with a correct name, but as they showed limited information I couldn't be 100% certain of either being the right person. Plus he has a middle name which didn't show up on either indexes.
