Hi Jesse,
The Civil Registration of births, marriages and deaths only started in England and Wales on 1st July 1837. Before that date these events were not formally registered and we are dependant on the baptisms, marriages and burials registers kept by each parish where the event occurred.
As a result there is no formal marriage certificate for Richard and Frances.
There is a transcribed record of the event on the Family Search site (this is a free resource with millions of worldwide events recorded and it is run by the Church of Latter Day Saints. You can search it for free - but you need to register with the site first.
The website is here;
https://www.familysearch.org/search/The record for Richard and Frances's marriage is attached to this message for you. As you will see in the parish records we don't receive the same amount of information that is included on the later, formal certificates.
The actual parish registers for the church concerned are probably held at Herefordshire Archives, but these are unlikely to show any additional information I'm afraid. Hence the further back we go -
we have no census records with names before 1841 -- and we have no formal certificates before July 1837.The next thing you can search for on that Family Search site are other children born to Richard and Frances (I think LadyHawk may have already posted the details of these) --- then search for the baptisms of Richard and Frances -- again try the Family Search free website.
Good Luck with it Jesse.
