Bill and Jean Adderley & family

Bill and Jean Adderley founded home furnishings retailer Dunelm after setting up a market stall in Leicester, U.K. in 1979.

There are now 173 Dunelm stores across the U.K.

They took the company public on the London Stock Exchange in 2006.

The Adderleys own 43% of the business, most of which is held by the couple's son, Will Adderley, who is Dunelm's deputy chairman.
