hi there, have looked at your request, as my dad had a friend in the regiment (but in later years). The Queen's Royal Regiment was known as the Royal West Surrey regiment, when your grandfather was serving. As he survived the war, he was very lucky, because less than 20 men did who were with the 1st Battalion in 1914. I can tell you that the 1st battalion landed at le Harve in August 1914 and remained on the western front for the entire war.
You might find additional information on your grandfather, as as survivor from the regimental association. They can be contacted at the following address:- Surrey History Centre, 130 Goldsworth Road, Woking, Surrey GU21 6ND, 01483 518737. E.Mail: email@example.com
