I found a civil death certificate for someone who died in 1874 in the townland of Cooneen, Co. Tipperary.
The registrar wrote the informant's name and underneath put this:
"Present at death.  Occupier deceased Cooneen".
But he had already recorded that the deceased man was from Cooneen, so why would he also make this indication under the informant's information?  I haven't seen that on other records.
Also, the deceased man was named James Corbett, but the informant was named John Ryan.  Since he was present at death, should I assume that he was closely related to James Corbett?  James was married but his wife's name is not recorded, and I guess I expected that she would have been the informant normally.
