I guess you are referring to the NSW BDM online index for those two deaths. It could be that neither is your chap, as the details on any NSW dc from that era depends on the informant’s own knowledge, and on the indexer’s accuracy in reading the handwriting.
I note that the NSW online index gives limited info :
1911 registration (#9556) George MORRIS, parents given names as George & Elizabeth, registered in the Canterbury District.
1915 registration (#18745) George W MORRIS, parents given names as
William & Elizabeth, registered in the Liverpool District.
http://www.bdm.nsw.gov.au/familyHistory/familyHistory.htm The NSW BDM gives links to their official transcription agents. This is an alternative way to obtain all the details on those NSW BDM certificates, without the official (and more costly) certificate. The official transcription agents can send the transcriptions via email attachments.
Information on NSW BDM dcs includes (of course depending on the informant’s knowledge)
The deceased’s marriage/s and details about the children of each marriage, where/when the deceased was born, where/when married, how long in the colonies/states, etc as well as the medico’s statement for cause and duration causing the death, AND the burial information.
There are of course other deaths registered in NSW for people with the name George MORRIS, some only give the age and location.
ADDING I can see that in 1913 that the NSW Electoral rolls had over 50 chaps registered as MORRIS, George. It was not compulsory to enrol, but all that were enrolled were British Subjects aged 21 and over.
Do you have any other details to give you confirmation as to where and when you chap was alive (marriage, birth of children, etc)
