you could get a copy of the parish marriage from the record office in Carmarthen. Don't be put off by the price for research, you have the date & parish for the marriage, so no need to pay for research &the archives should be able to provide a copy.
Your family could have been non-conformist and married & buried in the parish church. Not all places of worship have a burial ground & so there's no choice but to use the parish burial ground. From the start of civil registration, marriages could take place in a place of worship other than a parish church, but a registrar had to be present. This was the case until the 1890s. In rural areas, it may have been easier to marry in the parish church rather than get a registrar to attend.
Be thankful you're not related to that Duke of Sutherland - not a popular man becuase of his involvement in the clearances. His statue still gets vandalised.
