Edit to add: I now see some of these already posted by wivenhoe, but as I've typed them I'll leave them up.
This looks to be the birth mentioned by clancam
Name:
Dennis Quinlan, Dennis
Parents: Quinlan, Cornelius
Mother: Mcdonald, Margaret
Date of birth: 24 May 1862
Registered:
Launceston,1862
Record ID:

Resource: RGD33/1/40 no 216
Again, the father has signed with a cross, and his occupation is given as 'groom'
It is not unusual for there to be mistakes in registration, especially when the informant is illiterate. Speculation: Perhaps the registrar asked "Name of father?" and perhaps Cornelius is the name of the father's father.
And this death with the different father's name, but the age of the child fits the above birth.
Denis QUINLAN, died 16 June, 1862, aged 3 weeks, groom's child, cause of death: diarrhea. Informant was the father, Denis QUINLAN, who signed with a cross.
Registered, Launceston
