Hi Ron
Welcome to Rootschat

You need the information if you are going to order copies of certificates from the GRO at Southport.
MQ= March Quarter (events registered in Jan/Feb/March of the year in question)
JQ= June Quarter (events registered in April/May/June of the year in question)
Paddington has the volume number 5d
669 is the page reference
The freebmd project hasn't got as far as the dates you are looking for so the information has come from a subscription site (such as Ancestry) who are hosting the images of the birth marriage and death indexes.
The death index is under England & Wales Death Index or England & Wales Freebmd Death Index, Oscar is on the first (search through the images) but not the second (I think they have used OCR programming on the 2nd to get all the names and it can be 'hit or miss')
