I'm looking for information on the arrival of Hannah HEDGE or HILL to NSW Australia between 1851-1853, with infant son.

I have information on her prior to 1851 and after 1853 as follows,

In 1851 Census she is with her parents in Bedford Befordshire England she was born March 1834 Bedford Bedfordshire England.

Her son George Woodward HEDGE was born 8 June 1851 Bedford Bedfordshire, reputedly the son of George Woodward of Bedford. However there is no proof of this.

Hannah then appears in NSW where a second son Thomas HILL is born 28 August 1853 Petersham NSW his father is named Samuel HILL, but I can't find proof of any marriage either in England or in Australia, her youngest son George Woodward HEDGE is with her in NSW.

Hannah then married Henry BEZER in 1854 Willoughby NSW Australia and Thomas was baptised as Thomas Bezer-Hill but he continued to use the name HILL for his marriage and for his children, strangely George Woodward HEDGE Hannah's first son was not baptised Bezer but remained HEDGE.

On Hannah's will it states that she leaves her property to her two natural born sons George Woodward HEDGE and Thomas HILL as well as her other BEZER sons.

I can't find any reference for Hannah arriving in Australia between the Birth of George and the birth of Thomas as HEDGE/S or HILL/S. I have even tried HUMPHRIE/S and HUMPHREY/S which was her mothers maiden name, I have also tried various combinations of her name Ann/Anne/Anna/Hanna etc. but nothing.

Hannah's older brother Samuel Hedge arrived with his wife Sarah nee Ives and two small children in 1856 on the Blackfriar he listed Hannah as sister living in Sydney.

If someone could find her entry to Australia it would be much appreciated.
