Here's one: From Wiltshire, England, Church of England Marriages and Banns, 1754-1916
These are the banns rather than the marriage but may help:
James Provis
Bann Date:   11 Oct 1840  (third calling) 
Bremhill, Wiltshire, England
Spouse:   Sarah Webb
James was of this parish and Sarah of ? Malford, so the marriage may have taken place there.
