I am researching Albert Percy Hack(1893) who is the son of Albert George Hack(1868-41) and grandson of Betsey Hack nee Taylor on Ancestry and have a WW1 Medals hint but can find no more information. On Fold3 even the information Ancestry has does not seem to exist. He was awarded the British War Medal and Victory Medal and was a Private in the Royal Fusiliers. His Regiment Number was PS1566, for Company it just says WO329 which I think just refers to the medals.The Theatre of War dates are 14-11-15 to 22-3-16 and he was discharged to Commission 4-8-16. I would be e grateful for any more information as this particular branch of the family seems to have a number of males who served.
If it helps in the 1911 Census he was a boarder in Rednal, his parents lived in Bournville.
