I haven't delved that far as yet, but here goes...

John Wright Preston was transported to Australia from England in 1837 - have info on ticket of leave, etc if anyone interested... He married an Aboriginal woman Mahrahkah (or Molly Walcotte) and had at least one child, Charlotte (1829 - 1871), who married James Hyde 1817 - 1899). They had 9 children, one of whom is William (1860 - 1903), my great great grandfather. He married Mary Anne Ada Hughes (? - 1919) in 1886 and they had at least 5 children, one of whom was Charlotte Katherine Elizabeth Hyde (1884 - 1913). Charlotte married Frederick Burns (? - 1955) and had at least 4 children - Jemima (1911 - 1970) being my Grandmother. She had at least 7 children, with her husband, William John Watson (1900 - 1977). My dad is the youngest of these and is still very much with us...

If you can fill any blanks I'd appreciate it - I do have some additional info, but would like to go back earlier if possible...
