Hi Annie
Thanks for your reply but it is not the man I'm after. John was born in 1834, he is not shown with the rest of his family in the 1861 reply you sent me (about his brother Richard M Rees). A possible explanation for John's absence in 1861 was his military career. I have a note that "he served in the New Zealand wars of 1860/61" I have John's 1871 census entry, living in London.
