Di, Are you looking for the GRO reference to enable you to order marriage certificates? Or the actual marriage details from parish records? You can search yourself for the GRO using the following link: _http://www.ancestry.co.uk/search/rectype/vital/freebmd/bmd.aspx_ (http://www.ancestry.co.uk/search/rectype/vital/freebmd/bmd.aspx) If you are looking for the parish records you will have to be more specific as Amesbury registration district covers many.
