Page "Clapham" Paragraph 7

According to the history of the Clapham family maintained by the College of Heralds, in 965 King Edgar of England gave a grant of land at Clapham to Jonas, son of the Duke of Lorraine, and Jonas was thenceforth known as Jonas " de Clapham ".

The family remained in possession of the land until Jonas's great-great grandson Arthur sided against William the Conqueror during the Norman invasion of 1066 and, losing the land, fled to the north ( where the Clapham family remained thereafter, primarily in Yorkshire ).
