In an episode of the Dutch television showVerborgen Verleden (similar to the BritishWho Do You Think You Are?) broadcast in November 2014, the Dutch architectJan des Bouvrie found that his family was descended from Jehan de le Bouvrie (born about 1480), ofSainghin-en-Mélantois, where in 1543 his widow, Jeanne de la Motte, inherited a farm with four cows and two horses. A grandson of Jehan, the merchant Lawrence de Bouverie, born in Sainghin, migrated toEngland, where his descendantWilliam des Bouverie was created abaronet and became the ancestor of the Earls of Radnor. Jan des Bouvrie hoped to meet the present-day Lord Radnor, but he would not agree to meet him for the television show.[6]
