Dear Janilye,
Thanks for you interest. The info you have given me is alredy known as I made an Ancestry query and the girl who reponded had my Stanly Fairfax Owen as a 'fringe dweller' on her tree. My query sparked her interest and together we collated much of the info which is now on her tree (Lyons Family Tree). However I am really keen to: 1) trace Stanly's movements from Childhood to when he was supposed to have 1st gone to New Zealand in 1848; 2) discover if brother Frederick Charles travelled with him as they ended up living in the same place; 3) discover what happed to Percy Fitzwilliam who was supposed to have been involved in a shooting scandal - shootong his Eurasian princess wife. I believe he actually ended up in NSW, marrying in a town just over the boarder from where his brothers eventually lived; and 4) what happened to Henry Norris who I suspect may have remained in England.
If you happen to come across anything on these Owen brothers I would really appreciate it.
Thanks again, Jenny
