What we have is John Oddy (no birth or parents known)marrying Hannah Littlewood (born abt 1818 Yorkshire) on the 4 Apr 1836 at St.Peter Leeds Yorkshire England (IGI).
They had son's
Charles born abt 1837 Leeds
John born abt 1839 Chris. 9 Jul 1839 Leeds Par. of St Marks
and then sometime after this date left for Australia because another son William was born on the 10 Dec 1841 in Tumut NSW Australia.
We can't find the family coming into Aust. but obviously they did or my wife wouldn't be here now.
If I can get some help from a good detective out there. Could they have been in England when the 1841 census was taken with William being born Aust. Dec 1841? How would I find out John (senior) as well as Hannah's birth date.
