hello phil
thank you for your reply ive had a look at the yorks website and have narrowed the dates down when clifford was captured to the 25/26 or 27th of may 1918 during the german offesive on the river aisne .the yorks were in camp between the 16th and 25th of april which covers the date roy gilbert was transfered, maybe clifford moved at that or simular time
im sorry no i dont have ancestry but thank you for posting thre link
thank you all for you time and effort
