Hi,
So Ladyt.
The picture as it stands is..
You believe the parents of HENRY/HARRY SHEPPERSON were SAMUEL & JANE SHEPPERSON.
I am guessing you have some evidence for this
You have seen GEORGE SHEPPERSON'S death with the parents SAMUEL & JANE and wonder if they are brothers.
You say you have evidence of a brother of HENRY/HARRY named GEORGE (Initial posting)
To this point, no connection between the two has been discovered

The purchase of the certificate for the death of GEORGE in NSW (per reply #1) will give you a lot of information if the informant had the knowledge and may be the only way to confirm a relationship.
