I assume this is the marriage of your grandparents, so kn ow you know the names of two of your four grandparents
Name: Gladys A Packham-wilding
Date of Registration: Jan-Feb-Mar 1947
Registration district: Maidstone
Inferred County: Kent
Spouse: Wiliam F Cox
What you can do now if you have not got it is get the marriage certificate to find the names of their parents. You could also search the death indexes to find when they dies and thus calculate their approximate birth dates and then search the indexes for suitable births
Until you get back before 1911 it is a bit more difficult to find things so it has to be a step at a time
Most of the indexes are online at
www.freebmd.org.uk (note this only gives very few details and you may need to buy the certificates to get more details)

Albert Wilding 1890-1971 may also be Herbert Thomas Wilding-Packham (born Herbert Thomas Packham) possibly the adopted son of James Charles Wilding and Clara Elizabeth Hinkley ? This will need to be checked in depth
hope that helps for starters
