Hello jennifer28,
The Argyll & Sutherland Highlanders (A&SH) are based in Stirling Castle, Stirling, Scotland. They now form the 5th Battalion of The Royal Regiment of Scotland.
As IMBER has posted, we would need a bit more information. My grandfather served in the Argyll & Sutherland Highlanders during WW1. I was lucky enough to find his service records (on Ancestry) but I already knew his age, date he enlisted & date of his death in 1917. (Killed in Action, Arras, France)
Regards, Dod.
