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.
