Since I first looked at the Fitch family in Maitland in 2004 I've found I was following the wrong Fitch family. There were two men named John Fitch in Maitland.
My John Fitch married Honora Cleary, went to Charters Towers, Queensland, changed his surname to Fitz and, when Honora died, married again and had many children whose descendants live in the Townsville rea.
I'm sorry to ay I have no relationship to the descendants of John Fitch and Harriet.
Thank you for making contact.
