Thanks for input, yes, the PRONI abstract entry has him at what was his usual address, no other address mentioned. Will cross check my notes to see if I have previously looked for a death notice for him on the newspaper microfilms I searched before - if not, will check when I next get opportunity. Was just interested to see his cause of death and who of his family, if any, was present. Again, no obvious thoughts as to why they wouldn't have registered it. No known estrangement with them and assumed it would have been needed for his burial. Maybe if anyone looking in on this thread is heading to PRONI soon, they could PM me for details and kindly check the record associated with the online abstract.Meantime, as Elwyn has suggested, I will contact probate office and ask if they needed sight of a certificate back in 1923.
