I too have ancestors named TURNER from Old Brampton, but they don't seem to fit in with yours. However, did you know that the TURNER's were orignally at the Adelphi foundry at Sutton-cum-Duckmanton and my particular branch moved to the foundry at Old Brampton (both foundries at Old Brampton and Sutton-cum-Duckmanton were owned by the Smith family of Sheffield) after the Aldephi foundry closed, and then when money problems shut the Old Brampton foundry in the 1830's, my particular branch of the TURNER family moved to Andrew Handyside's foundry in Derby. I have posted other information regarding these foundries onto a different topic on the forum today concerning a request in the Derbyshire Lookup Requests for "Sutton-cum-Duckmanton Parish Registers - REVILL). We may find a link between our families, you never know!
