According to the Cudgegong rate books 1860-1905, John Mawbey rented the premises for five years, from 1878-1883.
The store was located in Market Lane (now Street), West End, Mudgee.
In 1875 he had married 19-year-old Sarah Ann Maria Clarke at Mudgee Church of England when he was 26.
How long he had been in the town beforehand, and what he did until 1878 is still unknown.
According to Mudgee Historical Society, the Clarke family had land on Lawson's Creek, just out of Mudgee.
In 1883, John Thomas Mawbey took up a 'selection', farming land, at Breelong near Gilgandra in the state's Central West.
He subsequently became a prosperous farmer, accumulating more land, a total of 1500 acres in 1900.
It was John's wife Sarah and three of their children who were murdered at the Breelong homestead by Aboriginal man, Jimmy Governor and others in July 1900.
In his evidence to the court at the trial of Governor, John Thomas Mawbey stated he had resided at Breelong for 17 years, i.e. since 1883.
