Hi Yvonne
To research your family during their time in England, the best clues will probably be on the marriage certifcate. Do please post all the info on the certificate ie. name, ages, marital status, occupations, addresses, fathers' names & occupations and the names of the marriage witnesses.
With this information, it will, hopefully, perhaps make it a little easier to locate them somewhere for you.
Best wishes
