In 1847, as 'Lawrence Mawby' he married Ann McCulloch at St James Church of England, Sydney. [According to one of their descendents, this happened just three months after he arrived.]
They had two children in Sydney, Sarah and Mary Ann [according to a descendent of the latter].

On 19 February 1848 he was sequestered for insolvency.
At that time he was living in Pitt Street, Sydney and was a horse dealer.
Lawrence and Ann Mawby then moved to Queensland [correction: New Zealand, then England, then Queensland].
There are no records of any children born to them in either the NSW or Queensland Births Deaths and Marriages indexes.
However, the Queensland State Archives Index to Land Orders 1861-74 lists the following entries for 'Mawby' in 1864:
Lawrence, Ann, Sarah, Edward, Emily, Mary Ann, and Robert.
Another QSA index indicates that three 'selections' of land were awarded from 8 April 1868 to 31 March 1887 to:
Lawrence Mawby at Brisbane
Robert Mawby at Townsville
Robert Mawby and August Kuhn at Townsville
On 6 January 1866, their daughter, Sarah Mawbey, married John Thomas Phipps in a Particular Baptist Church cememony at Fortitude Valley, Brisbane.
Judging from her age when she died, she was born in 1847, the same year as her parents marriage, suggesting she was their first child.
She was 19 when she married.
Sarah's husband, Phipps. had come to Australia when he was 10 with his parents and older brother in 1857.
[see their story on Sarah Mawby & John Thomas Phipps]
There are several digitalised newspaper articles from the National Library of Australia that mention Lawrence Mawbey.

The Queenslander, Brisband, Saturday 22 November 1873
SPORTS AT WOOGAROO LUNATIC ASYLUM.
.... Shortly before 3 o'clock about 120 of the male patients entered the grounds ... watched by about 40 of the female patients seated on the opposite side of the paddock...
Next came a race which the patients ought certainly to have appreciated, being what is known as a " crab race" (open to all) — man metamorphosing himself for the nonce into a quadruped, at least as far as the means of locomotion are concerned.
Of course the laughter was immense throughout, and loud applause (especially from the patients) greeted the triumph of the successful crab, Lawrence Mawbey, whose prize of victory was a photograph stand.
Mawbey was again victorious in the next event—the sack race—and succeeded in securing a portable telescope by a tack's length, or rather his own length, which he had to measure under the winning post to defeat the patient who scored the first two contests of the day.
It's not entirely clear if Lawrence Mawbey was a patient as members of staff also joined in.
According to the Queensland Births Deaths and Marriages index, 'Laurence' Mawby died in 1874.
His parents were Robert Mawby and Sarah Orm.
