Unknown Knole House history comes to light

A previously unknown chapter in the history of the family behind one of the great stately homes in England has been revealed.

The current Lord Sackville, Robert Sackville-West, discovered his great-great uncle Lionel Sackville-West had five illegitimate children with a Spanish dancer after finding photographs of the children at the family seat, Knole House in Sevenoaks.

He has now written a book about this chapter in the family's history.
