anonymous, you need to provide at least the information that you have for others to assist you. If you provide LESS than all that you know, then you should expect us to have LESS success than you have had. Why make it harder for people to help you?
If this person has a wikitree profile, then set it to have a public biography and populate it with everything you know that is relevant - and edit your question to link to it ! There are lots of people here that are keen to help but they need to know at least what you do.
==============================================================
Having said that (as I'm always up for a challenge) is this the marriage record of your parents?
If so, then I've discovered the correct location/country myself and can help you a little...
Groom: SHIPLEY, Norman R W V
Bride: POWELL, Ethel A
Registration district: Glanford Brigg
County: Lincolnshire
Year of registration: 1937
Quarter of registration: Jan-Feb-Mar
Volume no: 7A
Page no: 1557
One problem that you are going to have is that the event you want details of is very recent and may not be published yet (E.G.
http://www.findmypast.co.uk only has deaths up to 2005). A second problem will be; identifying the correct death record and thus burial, will need the correct birth year and the information that you've provided so far is not adequate. Four plausible birth records exist...
POWELL Ethel Annie England Northamptonshire, Thrapston 1900
POWELL Ethel Annie England Staffordshire, Lichfield 1902
POWELL Ethel A England Yorkshire, Hunslet 1910
POWELL Ethel A England Worcestershire, Worcester 1911
BTW I found Norman's birth and death records...

Assuming that Ethel was buried in our near Scunthorpe, then the most likely place to find the information that you want is probably:
the North Lincolnshire Council's Burial Registers that can be search by phone or in person (see website for details).
