They have one child, Lady Olympia Patricia May-Rose Onslow (born 7 July 2003).
Lord Onslow lives at,[2] owns and manages the Clandon Park agricultural estate.
[3] In April 2015 Clandon House burned down, and in that year Onslow said that he wanted the building left as a shell and for the insurance money to be spent on Wentworth Woodhouse, which needed assistance.
However Marcus Binney of SAVE disagreed,[4] saying "It would be a terrible waste to leave it as a ruin.
As for spending the money elsewhere, you'll be very lucky if the Government don't snaffle it to rebuild the Houses of Parliament".
