Harold's burial was recorded at Wisley Surrey, he was of St Martin's House, Pyrford age 13.Buried 14 May 1923
I looked up St Martin's House 1920-1925-and it was a home for crippled boys where they were cared for and taught a trade. Depending on when Harold was sent there the website has group a photo taken 1921.
It has a list of the first 30,000 children and Harold Edward Ernest Cain is on the list. His file is CF/25760 and his dob listed as 13 October 1909.
As the hundred year mark is passed you can request a copy of his file. email
