David, you say you are new to all this. To explain: FreeBMD is compiled from the old GRO indexes, which are the only ones available for marriages until the GRO decides to produce a new index, as it has done partially for births and deaths. Marriages are grouped as four per page number up to 1851, then two per page, but the spouse's surname is not included until 1912, so to establish who married whom, checking the next census is often useful.
FreeBMD has a very flexible search engine, more so than the new GRO indexes, but the latter include more information about mother's maiden name and age at death. So you need to use various available sources to gain the maximum information.
