Thank you also to Elwyn Souter, Boo, Josey and Berlin Bob for all your help with this.
What a heartfelt inscription he has according to the interpretation.
I have been thinking about this and I agree with Shaun that this on FamilySearch surely cannot be right about him dying in Austria. His death seems to have been registered in Tyneside (I have no doubt he is Johann) so he must have died here.
As for the start of the inscription 'I Zeug' meaning 'stuff' - I have been thinking a few things on this. Firstly could this translate roughly to 'here is some stuff on Emele'. However, that would seem a bit blase to put on a memorial. Could it be his nickname? Although, I am not convinced about this either.
I am also wondering if he might have been a sailor/traveller and if more than one person in the party died and there may have been a mix up with names when providing the inscription. Perhaps there is an 'I. Zeug' buried somewhere is the cemetery in an unmarked grave?
Anyway, it might be that Johann had money (or someone else had on his behalf) as he has a purchased grave with a reasonably sized memorial (albeit a plainly designed one). As there is a gap between the top and bottom inscription, I wonder if this was deliberate, perhaps with the thought in mind that his family may have wanted to add something else later on, but this never happened.
When North Shields local studies reopens again I will be able to check out the actual burial register and I will get back on here and will enter on Find A Grave whatever I find in the entry. Hopefully, there might be more clues in the register.
I have remembered something else - this memorial is in section J which is Roman Catholic.
I will be updating this memorial at some point today and will add a postem to his freebmd entry.
Thank you once again to each of you who have posted. I really appreciate the time you have given and your thoughts and help with this.

Added: I have now updated the memorial on Find A Grave this morning. I have also now added a couple of postems to his entry on Freebmd. These postems may not appear though for up to 24 hours. It is good that there is information out there now for him for any of his family descendants who might want to find him. Thanks once again for all help.

Added: I have since received some more info from someone else. Apparently on Find My Past it shows he died in the infirmary. I wonder if this might have been Tynemouth infirmary or alternatively the Tynemouth workhouse (hospital)?
