Does anyone have any information about a James Bann born about 1780?

He married an Ann Jones (born about 1769) on February 27th 1808 in the English Bicknor parish chapel; witnesses were Susan Aston and Edward Aston.

James was my 3 x great grandfather, and I can not find any more details about him or his wife, although his marriage certificate and children's baptism records indicate that he was a miner.

Can anyone help? Does anyone know whether the colliery records are available for instance?

With thanks,

Lorraine.
