James was the father to William,in a newspaper article for 1828 James Rowntree lost an eye in an explosion at his gun shop in B/C it blew the shop front out,I always thought Rowntree
was just a retailer who put his name on other peoples guns,but Iv'e seen reference to "Rowntrees improved lock",more research needed.
Penrith is just over the hill (40 miles) from Barnard Castle. Graham.
