Dear Philippa, I am the great-grand-daughter of Michael O'Brien who owned Tinowon and lived there for 42 years. Sarah Jane was his sister. I am writing on behalf of my mother, Veronica O'Brien Sitton who was Michael's grand-daughter and the daughter of his son Wilton. She is elderly and legally blind, so has asked me to write. She would like to refer you to the Australian Biographical and Genealogical Record 1842-1899, vol. 1 and the ABGR, Series 1, 1788-1841*. In the first she has written an entry on Michael O'Brien of Tinowon,p.200. In the earlier book, there are entries on many of his ancestors. You can look up Lynch (John & Margaret Jane), O'Brien (Michael 1, Michael 2 and Johanna), Pendergast (John & Sarah Jane), Williams (Jane)
We hope this information will help you get to know better our family.
