Thanks for posting this Alan. William Sharp is actually a relative of mine, on my mothers side of the family.
William's Dad, Albert, was a Dover Harbour Board Tug Mate and looking through the family history William's relatives are listed in the 1861 and 1871 census as residing at the time at the Commercial Quay Hotel, Dover and the Pelican Inn, 159 Beach Street, Deal respectively.
William was educated at St Mary's School and the St Mary's Old Boy's used to visit his grave, the words on his gravestone read: William Sharp. Shot at Bondues, Nord on 27 August 1943 at the age of 50 years
I believe his first daughter Doris has died but not sure if Elaine is still alive
