The attached picture (printed on tin) is in an old family photo album, but it does not include any identifying information besides the uniforms themselves. We have reached a point where we are at a loss for identifying the two individuals and hope that some of the experts in this community can help identify the units involved and the timeframe of the picture.
The photograph is from a family line from Edinburgh, Scotland. We have a known ancestor from that line named Lance-Corporal John Auld that served in the 1/7th Royal Scots before he died in service in 1915. However, we believe that the photo was taken before our direct ancestor immigrated to the U.S. in the 1890s. Any help or insight would be greatly appreciated!
