The family name was Jackson, the children were Clara Harriet b 1881, Ernest Albert b 1882, Robert b 1884 and Rosa Lily b 1885. The two younger children were baptised within a month of their deaths so that led me to think it was an illness rather than an accident, but I may be wrong.
Was there any kind of epidemic raging that might have affected them? Smallpox or influenza perhaps.It obviously didn't cause many other deaths in the village that year but may have done in the wider area.
Their father was a miller, their address was Cottage by mill at Keswick and they were all buried in Intwood. I suppose a flood is a possibility but it would have certainly been reported in the newspapers if it caused the deaths of so many children.
Would a death certificate from 1887 be accurate as to cause of death?
