Hmmm - so we have at least two Josephs - which one are we looking for

The one who died, registered at Newcastle 1914 - son of Clement and Sarah.
According to the newspaper death notice this man was aged 73 giving a birthdate abt 1841.
The one Sue found d 1928 in Qld - son of Ezra and "Forbes".
The age at death is given as 76, thus a birthdate abt 1852.
So the names for parents for the 1928 death are not correct?
I'm confused................... I think I am anyway.
