The Early Years

The two Lewis schools trace their history to the will of their founder, Edward Lewis, a wealthy aristocrat, who traced his ancestry to Gwaethod Fawr, Prince of Cardigan in the tenth century. Despite his privileged upbringing, Edward Lewis was mindful of the poverty and deprivation in the lives of ordinary people, and so, in his will of 1715, he made provision for the education of "fifteen poor boys". It is believed that by 1853 the foundation catered for the education of girls, but at an elementary level only.
