Hi
Have you only looked at the partially transcribed index on freebmd?
http://freebmd.rootsweb.com/ Transcriptions for those years are very thin on the ground
You will need to search the full GRO index which is available at your nearest main library if you live in the UK. It can also be searched online if you have an Ancestry subscription or at
www.findmypast.com which is a paysite
Without knowing Glady's surname you face a very time consuming task as only the spouse's surname is shown alongside the entry - not her christian name
There is potentially a 20 year period involved which means downloading 4 images per year and searching for a Maurice Rose entry on each image
There will probably be more than one entry but using the reference and surname of spouse, you will have to download the corresponding image to see if she was a Gladys
