Here's some more thought provoking discussion.

His son Isaac married Sarah Ashburn, and died 1882 • Muswellbrook, New South Wales, Australia (NSW BDM 9158/1882 (MOSES)). So not the Isaac that married Sarah Symons.
I have not been able to discover any further information about my Isaac's parents other than their names Abraham and Rebecca COHEN.
