Hardwicke’s Marriage Act of 1753 introduced most of the features of the Rose-style marriage register. In fact Rose’s Act explicitly stated that ‘nothing in this Act contained shall extend to repeal any Provision contained in an Act passed in the Twenty-sixth Year of the Reign of His late Majesty King George the Second intituled An Act for better preventing Clandestine Marriages’.
An Act for the better preventing of clandestine Marriages -‘Hardwicke’s Marriage Act’ (1753) An Act for the better regulating and preserving Parish and other Registers of Births, Baptisms, Marriages and Burials, in England (1812).
The keeping of registers of Banns was a requirement of Hardwicke’s Act and before 1813, the record of the calling of the Banns was frequently recorded in the same register as the marriages. From 1813, there should be separate registers. If the marriage was by Licence, you should be able to find the relevant bond or allegation (the Licences themselves don’t usually survive) which may provide some additional information. If nothing else, you may get the name of a bondsman, usually a friend or relative of the groom.
