I think we are definitely looking at two different Charles Williams and therefore two different Henrys. I believe my Henry is the son of Charles who married Catherine Malone, the widow of the Norfolk Island Superintendent, John McDavid. I have Charles' 3 step daughters Mary,Eleanor(Ellen)and Catherine marrying in Sydney which is a very good indicator the family left Tas and how Henry came to be married in Bathurst.
I would like to know what records other than TFL/IGI you have that connect your Henry,who marries Helen Aherne, to Charles and Catherine as I eliminated Helen very early in my research:)
