Hi Cando,
I'm working this branch back at the moment and it is the most eventful one I've found records for so far. It is an interesting period for this family, as Isaac, the father, had a lamp shop in Jermyn Street, St. James's Palace, London. However there was a fire in this street, reported on February 9th 1840 and his shop was damaged and stock uninsured. By 1842, Isaac was a debtor. I'm surmising that this event really scuppered the family.
Any other help that you could provide would be just great. I've just emailed a relative, another distant cousin descended from Claud Behenna. He's come across a record saying that a photo was held of James Poole. Based in the UK and this being my first foray into Australia, I'm wondering, if the last school where he was teaching would have a copy, as my cousin isn't sure where the original info came from...
I'm really delighted with this extra information that you've provided, as before this weekend, these ancestors were all just words!
Best wishes, Jimmijam
