Hello Nick, You are on the right track, going back one step at a time. It will be easier as youuget further back in time.[sometimes!]. You can search for the marriage of your grandparents, online, via < Lancashire bmd's> or <1837 online>. Also at any LDS Family History Library, [open to any person] that have the GRO indexes.[also known as St. Catherine house indexes]. Once you get that you will have information that will take you back, via the 1881 census,[online via <familysearch.org>] .Other things to access will be the 1901 census online, and the 1891 census, [index only available via <ancestry.com> Pay site,and expensive.] Some LDS centres have the 1891 census on Fiche, with a street index only. Some listers may have access to indexes, and would give you some help there. Hope this has been some help to you. Yours in Genealogy, Jan Researching Parry ,Tonge, LANCS.
