Private Sidney Albert Coe, was the eldest son of Richard and Mary-Ann Coe. He was born in 1886 in Stopsley, and worked as the Clerk for Messer’s Howe and Byfield Coal Merchants on King Street.

The nature of his death is unusual for a military casualty being that he drowned whilst swimming in the sea at 11:30 AM on 28th July 1917, at Hopton on the UK East Coast. Two men from the company tried their best to rescue him, but he was taken by the sea, and his body recovered the next day after a search by Navy inshore boats.
