I have found some of my family's Baptisms, Marriages and Burials on this site but some are missing eg my ggrandparents Thomas Williams and Amelia Walker's Marriage. It is listed in the bmd on ancestry as being ond 1878. Could the reason for this be that they married in one of the many chapels (in St Briavels area at the time) and not in the Church?

Any info much appreciated

Regards

Alison
